[Android] Bumped Android Gradle plugin to 7.3.1. Thanks to the PR from Rexios
- Updated minimum Flutter version to 3.0.0. Note that technically this was already a requirement by flutter_local_notifications_linux 2.0.0 as ffi 2.0.0 requires Dart 2.17 at a minimum and that shipped with Flutter 3.0.0
Added explicit ffi dependency that Linux implementation of the plugin was already using
Updated site used by example app to display dummy/placeholder images
Updated readme to warn developers that choose not to follow the official Android guidance around notification icons that using the @mipmap/ic_launcher resource requires additional release build configuration. Thanks to the PR from Daniel Arndt
Updated readme to add note about how Flutter has an issue with apps running with desugaring on Android 12L and above. Thanks to the PR from Mirek Mazel See flutter/flutter#110658. One potential fix added to the readme is for apps to add the WindowManager library as a dependency:

dependencies {
    implementation 'androidx.window:window:1.0.0'
    implementation 'androidx.window:window-java:1.0.0'
    ...
}
