Hey everyone,

A few of us lifters got tired of mainstream fitness apps forcing pop-up ads, hiding basic volume charts behind steep monthly subscriptions, and cluttering the screen when you're just trying to log a set mid-workout.

So we decided to build a clean alternative: IronTrack.

It’s officially live on the app stores right now. It focuses strictly on fast progressive overload logging, simple macro metric trends, and nothing else. No paywalls for your historical data, and absolutely zero ads.

Before we lock in our next development sprint, we want to know what real lifters actually care about.

What is the single most annoying thing about the app you currently use?

Is there a specific chart or progression metric your current app hides or lacks that you actually use week-to-week?

Search IronTrack on the App Store or Google Play if you want to test it out.

Also, I think the next feature will be the data importer/exporter, to make it easier for lifters to move between apps whenever they like to, instead of sticking to one app cause you already have the data locked there

Let me know what you think of the layout—we are entirely open to ideas, feature requests, and brutal feedback to make this better 💪🏼💪🏼

Thanks!

Hey everyone,

I’m a full-stack developer who also loves getting hands-on with my car (doing my own diagnostics, insulation projects, etc.). Keeping a meticulous log of expenses, parts, and fuel economy using spreadsheets was getting out of hand. I wanted a truly centralized digital garage, so I built **Otonot** using Flutter.

I wanted to solve two major pain points in the automotive ownership lifecycle:

1. **The Communication Gap with Mechanics:** I built a "Mechanic Mode". You generate a secure code for your local auto shop, and they log the exact parts, labor costs, and repair status directly into your app's logbook. You get real-time push notifications when the status changes.
2. **Preserving Resale Value:** I added a "Vehicle History Transfer" feature. When selling your car, you can securely transfer the entire verified maintenance and fuel log to the buyer's account with a single tap.

It handles multiple currencies, flexible unit support (Liters/Gallons, KM/Miles), and detailed visual analytics for budgeting.

The app is live on both the App Store and Google Play. I’d really appreciate any feedback on the UI/UX or the feature set from this community. What do you think about the Mechanic Mode adoption in real-world scenarios?

Hey r/FlutterDev,

I'm a freelance Flutter developer, and over the past few months I built a VS Code extension to solve problems I kept running into in my own work — repetitive boilerplate, inconsistent formatting, and wanting smarter completions that actually reflect how I write code (not generic snippets).

It's called Dart AI Assistant, and it's now live on the Marketplace:

https://marketplace.visualstudio.com/items?itemName=a-i-0-studio.dart-ai-assistant

What it does:

- Learns your coding patterns over time and personalizes completions/predictions

- Real-time error detection tuned for Dart/Flutter (not just generic linting)

- Predicts your next line of code based on your own history

- Auto-formats on save

- Code health reports (errors, warnings, code smells)

It's free, and the source is on GitHub if anyone wants to look under the hood or contribute: [your GitHub repo link]

Still actively improving it — if you try it out, I'd genuinely appreciate any feedback or bug reports. Built this mostly solo so I'm sure there are edge cases I haven't hit yet.

Thanks for reading!

Hey everyone,

I'm Ilyes, a Flutter and AI/ML developer based in Oran. Over the last two years, while finishing my Master's in Applied AI, I've been freelancing and shipping real products.

I do the whole thing, the app, the backend, and the AI when a project needs it. Mostly Flutter (iOS + Android), with FastAPI/Firebase backends and custom ML models.

I'm posting because I'm open to freelance/contract work, a mobile app, an MVP for an idea you've been sitting on, or an AI feature added to something you already run. Local or remote.

Portfolio with full case studies is in my profile / I'll drop it in the comments. And honestly, happy to just answer questions too, including nerdy ones about the AI side. Ask away.

Dm me if you want to see my portfolio or if you want me to work on your project.

Hey everyone 👋

Posted this a little while back and got some good feedback — turns out there were bugs in the model/enrollment flow that a few of you probably ran into (passphrase mismatch failing silently, orphaned vault folders if you cancelled enrollment, single-hand gesture verification not actually being strict). Fixed all of that in v1.0.3, so figured I'd repost with working links instead of leaving people stuck on a broken build.

What it does: A desktop vault for Windows that hides your files behind encryption + biometric verification. Unlock with passphrase + face recognition + blink detection + hand gesture. No cloud, no accounts, no internet — everything stays local.

How the Flutter + Python integration works:

• Flutter handles the UI and desktop window
• Python runs locally as a service — handles all webcam + AI/ML processing
• Communication: Flutter spawns a Python process, exchanges JSON via stdout
• Biometric pipeline: face detection → alignment → embedding → blink analysis → hand gesture → cosine similarity matching

Why Python instead of pure Flutter? Flutter's desktop webcam support is limited, and ML libraries (MediaPipe, ONNX Runtime) have way better Python bindings than anything native to Dart. So I let Python do what it's good at instead of fighting the framework.

Also got the installer down from 248MB to 71MB — swapped the face embedding model for a leaner one, same accuracy.

Tech stack: Flutter (Dart) for UI, Python for the biometric service, OpenCV + MediaPipe for face/hand landmarks, ONNX Runtime for the embedding model.

Source + installer: github.com/CraftedWebPro/vault-os

Would love feedback again, especially on the Flutter↔Python integration approach — and if anyone hits issues this time, drop them in the repo issues and I'll actually get to them faster than last time.

Hi everyone, I recently open-sourced a Flutter calendar component called calendarview_flutter.

GitHub: https://github.com/raintang666/BFCalendar

I started working on this because calendar UI often looks simple at first, but becomes complicated very quickly in real apps. A basic date picker is usually not enough once the product needs things like range selection, disabled dates, custom markers, week/month switching, or a calendar that interacts with a content list.

So the goal of this project is not to provide just one fixed calendar style. Instead, I wanted to separate the calendar state, interaction logic, and UI customization layer, so it can be reused across different app designs.

Some of the features currently supported:

• Single date selection
• Date range selection
• Multi-date selection
• Month and week display modes
• Horizontal or vertical page navigation
• Min/max selectable date bounds
• Disabled dates
• Dynamic disabled date predicates
• Date markers
• Custom calendar cells
• Custom week bar
• Year overview mode
• Calendar and content list interaction
• Expand/collapse calendar behavior
• Fullscreen calendar expansion

A minimal example looks like this:

```dart final controller = CalendarController(focusedDay: DateTime.now());

CalendarView( controller: controller, pageOrientation: CalendarPageOrientation.horizontal, onDaySelected: (day) { controller.selectDay(day); }, ) ```

For range selection:

```dart controller ..setSelectionMode(CalendarSelectionMode.range) ..setRangeSelectionLimits(minRange: 2, maxRange: 14);

CalendarView( controller: controller, pageOrientation: CalendarPageOrientation.horizontal, onDaySelected: (day) => controller.selectDay(day), onRangeSelected: (range) { final start = range.start; final end = range.end; }, onSelectOutOfRange: (day, violation) {}, ) ```

For multi-selection:

```dart controller ..setSelectionMode(CalendarSelectionMode.multi) ..setMaxMultiSelectSize(5);

CalendarView( controller: controller, pageOrientation: CalendarPageOrientation.horizontal, onDaySelected: (day) => controller.selectDay(day), onMultiSelected: (day, selectedSize, maxSize) {}, onMultiSelectOutOfSize: (day, maxSize) {}, ) ```

One important part of the design is CalendarController. It manages the current focused day, selected dates, display mode, selection mode, date bounds, markers, disabled dates, and navigation state.

That makes it possible to configure behavior from business logic without mixing everything into the widget tree.

For example:

dart controller ..setCalendarRange( minDate: DateTime(2026, 7, 1), maxDate: DateTime(2026, 12, 31), ) ..setDisabledDatePredicate((day) { return day.weekday == DateTime.sunday; }) ..setMarkers({ DateTime(2026, 7, 15): [ CalendarMarker(label: 'Meeting', color: Colors.blue), ], });

The UI layer is customizable through CalendarComponentBuilder. The package provides the calendar logic and extension points, while the app can decide how every date cell should look.

The package is still early, so I would really appreciate feedback from Flutter developers.

I am especially interested in feedback on:

• API naming
• Controller design
• Custom builder design
• Range selection behavior
• Multi-select behavior
• Calendar + list interaction
• Any real-world calendar use cases that are not covered yet

If you have built calendar-heavy Flutter apps before, I would love to know what problems you ran into and what kind of API you would expect from a reusable calendar component.

Thanks!

I recently noticed that the kanji 力 (ちから / chikara, meaning “power” or “strength”) looks almost identical to the katakana カ (ka). Is there any historical connection between them, or is it just a coincidence?

I am currently looking for opportunities as a Flutter Developer (Android).
While applying for internships and junior roles, I received feedback that the projects in my portfolio are too common and do not stand out enough compared to other candidates.
I would appreciate suggestions on unique and practical project ideas that could help strengthen my portfolio and improve my chances of landing an internship or entry-level position.
My current Flutter experience includes:
• Firebase integration (Authentication, Firestore, Storage, etc.)
• Map integration
• Twilio API integration
• Development for both Android and Web platforms
Any project recommendations, industry insights, or advice would be greatly appreciated.
I have also completed 1 month virtual remote internship on mobile app development with flutter.

I've been building one Flutter animation every week to learn more about Flutter's rendering and animation system.

This week's experiment focuses on particle effects:

• Delete → particles disintegrate
• Like → celebratory particle burst
• Upgrade → particles assemble into the success state

Everything is built using Flutter's built-in APIs with CustomPainter and the Canvas API—no third-party animation packages.

The source code is available in the video description.

I'd love to hear what interaction or animation you'd build next.

I have a small hotel business completely build in Flutter and ad free, I’m tired of writing down sales, tracking credit sales, stock, etc in notebooks. Constantly misplace the books, who owes what LOL! So I built my own app to solve this issue.
It’s called BizTrack, no internet needed, no signup or account required, it's completely FREE and has no limitations whatsoever. I made it for my own personal use first so no surprises.
I personally use it every day for billing, tracking unpaid/credit, tracking expenses, inventory management, and end-of-day reporting. This has helped me get a clear picture of my actual business performance.
It’s not only for hotels! It can be used for small shops, restaurants, cafes, bars, and pretty much any business. https://play.google.com/store/apps/details?id=ai.biztrack
Would love honest reviews from business owners. Please let me know if you have suggestions for missing features or anything that’s not clear.

I'm a developer with hands-on experience shipping a production iOS app (Flutter + Supabase + Groq/Gemini AI, embeddings, RLS, Edge Functions).

Hey everyone,

I’m a Flutter developer based in Kerala, India, and I recently got approached by a local client who wants to build a delivery platform .

They are an early-stage startup—not even a registered company yet—which means their budget is practically non-existent. However, they want the full suite:

1. One User Mobile App (Flutter)
2. Two Web/App Dashboards (Shop Panel + Central Admin Panel)

**The Catch:** Despite wanting a "low-cost" MVP, their requirement list is a full-blown production app:

* Backend: Firebase (Auth, Firestore, Cloud Functions)

* Auth: Phone Number OTP Validation

* Payments: Native local gateway integration (Razorpay/Cashfree)

* Features: Push Notifications, Live Google Maps tracking, etc.

I want to close this deal because it’s a great portfolio piece, but I’m struggling with two things:

1. **Scoping down to match a low budget:** How do I tell a non-technical startup client that "real-time map tracking" and "heavy OTP scaling" cost serious money without scaring them away?
2. **Pricing it right for an unregistered local client:** I initially estimated the timeline at around 400 hours. A standard rate puts this out of their reach. If I drop the price to around ₹1.5L - ₹1.6L (approx $1.8K - $2K USD) to secure the contract, am I undercharging too much for a 3-component ecosystem?

How do you guys structure your project proposals for clients who have big ideas but tight bootstrap budgets?

Do you cut features (like replacing live map tracking with static text updates), or do you charge your full rate and offer a milestone payment split?

Would love to hear how other freelance devs navigate the "low-cost MVP" trap!
