flutter bugsnag

flutter_bugsnag #
flutter_bugsnag is a library that helps to notify a Bugsnag project of a runtime application error. It is not platform-specific meaning the notifier will work on iOS, Android, or the web.
Getting Started #
To notify bugsnag of all uncaught errors in the application:

At the root of the application, import the library using import 'package:flutter_bugsnag/flutter_bugsnag.dart';
Hook up an anonymous function to FlutterError.onError.
In the anonymous function, initialize BugsnagNotifier by passing it the bugsnag project API key.
Pass the FlutterErrorDetails (usually the first parameter of the anonymous function) exception and stack to the initialized notifier notify method.

main() {
FlutterError.onError = (FlutterErrorDetails details) {
BugsnagNotifier bugsnagNotifier = BugsnagNotifier('the_bugsnag_project_api_key');
bugsnagNotifier.notify(details.exception, details.stack);
};

runApp(
...
);
}

None Error Notification #
It is possible to notify bugsnag of other less severer issues py passing a named argument to .notify
try {
/// Erroring code
} catch (error, stackTrace) {
bugsnagNotifier.notify(
details.exception,
details.stack,
severity: ErrorSeverity.warning,
);
}

Adding User Info to Error #
To notify bugsnag of the user that experienced the issue, call .addUser on the notifier instance.
notifier.addUser(
userId: 'USR123',
userName: 'John Doe',
userEmail: '[email protected]',
);

Gotcha #
There is a reported issue were FlutterError.onError is not called on some uncaught error cases. Some solutions have been suggested in the thread.
