Learn Flutter
Flutter
Core Flutter development — widgets, platform APIs, and the day-to-day patterns you'll use building real apps. Start here if you're new to the framework or want to go deeper on the fundamentals.
State Management
Provider, Riverpod, BLoC, and GetX compared head-to-head, with guidance on which one actually fits your app instead of which one is trending.
Firebase
Wiring Firebase into a Flutter app the right way — authentication, push notifications, and the gotchas that don't show up until production.
Architecture
Clean Architecture, folder structure, and dependency injection for Flutter apps that need to survive past the first release — not theory, actual production folder trees.
Data & Storage
Local persistence in Flutter — SharedPreferences, Hive, Isar, Drift — and which one to actually pick in 2026 now that two of the big names have gone quiet.
API & Networking
REST APIs, Dio, and JSON in Flutter — building a networking layer that doesn't turn into a pile of try/catch blocks scattered across your screens.
Solve a Flutter problem
Stuck on an error? Find a practical fix.
Running `flutter build apk`, `flutter build appbundle`, or launching on an Android device fails during the Gradle build phase, often with a message like `Execution failed for task ':app:...'` or `Build failed with an exception.`
Flutter Gradle Build Failed: Common Causes and Fixes
Push notifications sent via Firebase Cloud Messaging (FCM) aren't being received on an Android or iOS device running a Flutter app, even though the send appears to succeed from the Firebase Console or backend.
Firebase Messaging Not Working in Flutter
The app runs correctly with flutter run (debug mode) but crashes, behaves incorrectly, or fails to build entirely in release mode (flutter build apk --release, flutter build ipa, or flutter run --release).
Flutter App Works in Debug but Fails in Release
Running flutter build ios, flutter run on an iOS device/simulator, or pod install inside the ios/ directory fails with a CocoaPods dependency error.
