initializer 0.3.1

Automatically generate code for aggregate initialization code by annotating Dart variable/function/field/method.

This library is just a simple library for integrating initialization code.

Annotate code that needs to be initialized with @Initializer() to generate the aggregate function initializer().

Call initializer() at the beginning of your program (such as the beginning of main function), then the relevant code will be initialized;

Features

supported types:

• global variable
• global function without required parameters
• static fields of a class
• static methods of a class without required parameters

Getting started

1. Add the following to your project's pubspec.yaml and run pub get.

dependencies:
  initializer_annotation: ^0.1.0
dev_dependencies:
  initializer: ^0.1.0

2. Import initializer_annotation.dart from a file in your project.

import 'package:initializer_annotation/initializer_annotation.dart';

3. Annotate your code with classes defined in package:initializer_annotation.

• See example/lib/example.dart for an example of a file using these annotations.

• See example/lib/init.init.dart for the generated file.

4. Run dart run build_runner build to generate files into your source directory.
   NOTE: If you're using Flutter, replace pub run with flutter pub run.

Usage

• you can config the output file path/group order in build.yaml

  targets:
    $default:
      builders:
        initializer:
          options:
            output_path: lib/init.init.dart
            order:
              - default
              - group1
              - group2
  

• use global variable/function(without required parameters)

  @Initializer()
  final initVar = init();
  
  bool _inited;
  @Initializer()
  bool init() => _inited = true;
  
  late final bool _inited2;
  @Initializer(group: 'group2')
  bool init2() => _inited2 = true;
  

• use static fields/methods(without required parameters) of a class NOTE:Need annotate class name and field/method both.

  @Initializer()
  class InitA {
    @Initializer()
    static final initVar = init();
  
    static late final int _init;
    @Initializer()
    static int init() {
      _init = 1;
      return _init;
    }
  }
