analytics_events_gen

An easy generator for tracking firebase analytics events via type safe methods.

Add to pubspec.yaml

Check pub for the latest version:

dependencies:
  # ...
  analytics_event_gen: 0.1.0
dev_dependencies:
  # include build_runner, only used for code generation.
  build_runner: ^1.6.5

Create AnalyticsEvents class:

// analytics.dart

import 'package:analytics_event_gen/analytics_event_gen.dart';

// this file will be generated.
part 'analytics.g.dart';

class MyAnalyticsBloc {
  MyAnalyticsBloc() {
    // initialize generated events class implementation.
    // the generated code will simply transform the method name
    // into an `eventName` and pass it to your callback method.
    // you can then do whatever you want with it, e.g. send to 
    // firebase analytics.
    events.registerTracker((eventName, params) {
      FirebaseAnalytics().logEvent(name: event, parameters: params);
    });
  }
  
  final events = _$AnalyticsEvents();
}

abstract class AnalyticsEvents implements AnalyticsEventStubs {
  void trackMyUserInteraction({double myProp, String yourProp});
}

By default the library will use null safety syntax. This can be disabled using build.yaml file:

targets:
  $default:
    builders:
      analytics_event_gen|analytics_event_builder:
        options:
          useNullSafetySyntax: true

Run the build generator
