analytics_logger_gen 1.0.2

analytics_logger_gen generates an event logger for analytics tools like FirebaseAnalytics and AppsFlyer. Import data from Google Spreadsheets, remote repositories or CSV files.

analytics_logger_gen

analytics_logger_gen is a code generator that generates an event logger for analytics tools like FirebaseAnalytics and AppsFlyer. Import data from Google Spreadsheets, remote repositories or CSV files.

Running the generator

flutter packages pub run build_runner build

# if you want to delete the generated files before building
flutter packages pub run build_runner build --delete-conflicting-outputs

# if generated files are not updated after modifying the CSV file
flutter pub run build_runner clean

Basic Usage

The builders generate code when they find members annotated with @AnalyticsLogger.

import 'package:analytics_logger_gen/analytics_logger_gen.dart';

// Building creates the corresponding part 'analytics_logger.g.dart'
part 'analytics_logger.g.dart';

@AnalyticsLogger(
    // ex) (from project root)assets/logger_gen_example_sheet.csv
    localCsvPath: '<PATH-TO-CSV-FILE>',
    // When you declare the localCsvPath, the remoteCsvUrl is ignored.
    remoteCsvUrl: '<URL-TO-CSV-FILE>',
    
    loggers: {
      // COLUMN_NAME is the name of the column in the CSV file
      // The value of the [COLUMN_NAME] in the CSV file should be [TRUE] or [1] to enable the logger, 
      // and [FALSE], [0] or [NULL] to disable the logger.
      FirebaseAnalyticsLogger: '<COLUMN-NAME>',
    })
// The class should be declared private '_' to avoid conflicts with the generated class
// ignore: unused_element
class _CommonAnalyticsLogger {}

// You can declare any number of loggers for third-party analytics tools.
class FirebaseAnalyticsLogger extends EventLogger {
  FirebaseAnalyticsLogger();

  @override
  void logEvent(String event, {required Map<String, dynamic> attributes}) {
    // Do something with the event and attributes
  }
}

Example

Calling the generated code

AnalyticsEventsProvider.appStarted();
AnalyticsEventsProvider.mySendMessageClicked(
    title: 'hello', message: 'world');
AnalyticsEventsProvider.homeBottomButtonClicked(
    a: 'a', b: 'b', c: 'c', d: 'd');

CSV file

• The indices of the event_name and arguments columns cannot be modified; they are fixed at column indices 0 and 1, respectively. (You can change their names, but not their indices.)
• You can add any number of columns to the right of the arguments column.
• The values of the columns are used to determine whether to call the corresponding analytics tool.
• The value of the [COLUMN_NAME] in the CSV file should be [TRUE] or [1] to enable the logger, and [FALSE], [0] or [NULL] to disable the logger.
