call_ui_kit 0.2.0

A ready-to-use Flutter call UI kit for personal audio, video, and group calls.

0.2.0

Performance

• Cache CallStrings.english() as CallStrings.englishDefaults to prevent cascading widget rebuilds.
• Extract speaking border animation into isolated StatefulWidget — ParticipantTile is now a StatelessWidget.
• Keep SpeakingIndicator in widget tree permanently and toggle via visible parameter instead of destroying/recreating the AnimationController.
• Skip rendering SignalStrengthIcon when signal strength is excellent (the default).
• Cache screen sharer name lookup in didUpdateWidget instead of scanning participants on every build.
• Add RepaintBoundary to FloatingPipView child to isolate video repaints during snap animation.
• Remove _DefaultStrings sentinel class (~60 lines of boilerplate).

Bug Fixes

• Show remote screen share content in personal (1:1) call layout — previously screenShareWidget was ignored outside group calls.

Breaking Changes

• CallScreen.strings is now nullable (CallStrings?). Pass null or omit to use English defaults. Previously accepted a non-null CallStrings with an internal sentinel.
• CallStrings.englishDefaults is a new cached static field — use it instead of CallStrings.english() when a stable reference is needed.
