- 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
