Install sentry_flutter

flutter pub add sentry_flutter

Edit lib/main.dart and add SentryFlutter.init

import 'package:flutter/material.dart';
import 'package:sentry_flutter/sentry_flutter.dart';

void main() {
  SentryFlutter.init(
    (options) => options
      ..dsn='Your DSN here' // if hard coding GlitchTip DSN
      ..tracesSampleRate=0.01  // Performance trace 1% of events
      ..enableAutoSessionTracking=false,
    appRunner: () => runApp(MyApp())
  );
}

Set the following environment variables

• SENTRY_DSN - Your DSN here. Example: "https://0000@your-url/1"

  throw new Exception('an exception');
} catch (exception, stackTrace) {
  Sentry.captureException(exception, stackTrace: stackTrace);
}
