Convert 20 more single-file apps to the validated pattern: lib/main.dart
holds only the runApp + MaterialApp bootstrap, while a new lib/example.dart
holds the full screen (Scaffold, AppBar) and the focused example code.
Apps: enabling_splash_screen, getx_counter_app, image_from_network,
infinite_list, load_local_image, load_local_json, persist_key_value,
push_notifications, sliver_app_bar_example, stateless_widgets, tic_tac_toe,
tip_calculator, using_alert_dialog, using_edittext, using_expansionpanel,
using_http_get, using_interactiveviewer, using_snackbar, using_stepper,
using_theme
- Bump all apps to sdk >=3.0.0 <4.0.0 and add flutter_lints + a shared
analysis_options.yaml to every app (flutter analyze is now green repo-wide)
- Fix real compile errors in firebase_google_authentication and image_editor,
plus deprecated APIs (Matrix4, SvgPicture.color, textScaleFactor),
missing async 'mounted' guards, and misc lints via dart fix + manual fixes
- Align pubspec 'name' with each folder and Android namespace/applicationId
with the documented github.nisrulz.* convention
- Convert bmi_calculator from a legacy Flutter module to a standard app
with a proper android/ scaffold; fix missing android:exported in launcher
manifests across 22 apps so all Android builds pass
- Untrack generated build files (GeneratedPluginRegistrant,
.flutter-plugins-dependencies) and ignore them
