RecoverableApp class

A wrapper widget that provides automatic crash recovery.

Usage

void main() {
  runApp(
    RecoverableApp(
      child: const MyApp(),
    ),
  );
}

When an unrecoverable error occurs:

  1. The error is intercepted and fingerprinted.
  2. If a snapshot exists, the recovery screen offers "Resume" or "Start Fresh".
  3. If in a crash loop, a minimal safe screen is shown.

Custom Recovery Screen

RecoverableApp(
  recoveryScreenBuilder: (context, state, onRestart, onStartFresh) {
    return MyCustomRecoveryScreen(
      error: state.error,
      onRestart: onRestart,
      onStartFresh: onStartFresh,
    );
  },
  child: const MyApp(),
)
