Flutter Assets Gen

命令 (Provide commands)

• F1 > Search flutter assets
  • Flutter Assets: Watch
  • Flutter Assets: Stop Watch
  • Flutter Assets: Generate

如何使用 (How to use)

• step 1. 在项目 pubspec.yaml 下添加 (Add under project pubspec.yaml)：

flutter_assets:
  assets_path: assets/
  output_path: lib/constants/
  filename: assets.dart

• field_prefix 为可选字段，如果想去掉 assets 前缀，则提供一个空，默认为 assets (field_prefix is ​​an optional field, if you want to remove the assets prefix, provide an empty value, the default is assets)

flutter_assets:
  assets_path: assets/
  output_path: lib/constants/
  filename: assets.dart
  field_prefix:

• 修改 prefix (Modify prefix)

flutter_assets:
  assets_path: assets/
  output_path: lib/constants/
  filename: assets.dart
  field_prefix: resource

• 忽略注释 (ignore comments) #12

flutter_assets:
  assets_path: assets/
  output_path: lib/constants/
  filename: assets.dart
  field_prefix: resource
  ignore_comments: true

• 只选择部分文件夹 (Select Partial Folders) #10

flutter_assets:
  assets_path:
    - assets/images/
    - assets/msic/
  output_path: lib/constants/
  filename: assets.dart
  field_prefix:
  classname: R

• step 2. 生成文件内容 (Generate file content)

class Assets {
  Assets._();

  /// Assets for loginLogo
  /// assets/images/login/logo.png
  static const String assetsImagesLoginLogo = "assets/images/login/logo.png";

  /// Assets for tabHome
  /// assets/images/tab/home.png
  static const String assetsImagesTabHome = "assets/images/tab/home.png";
}

• step 3. 引入 (introduce)

import 'constants/assets.dart';
/// example1:
Image.asset(Assets.assetsImagesLoginLogo, height: 30, width: 30),
/// example2:
Image(image: AssetImage(Assets.assetsImagesTabHome,), height: 30, width: 30),

修改类名 (Modify class name)

flutter_assets:
  assets_path: assets/
  output_path: lib/constants/
  filename: assets.dart
  field_prefix:
  classname: R

生成内容 (Generate content)

// ignore_for_file: prefer_single_quotes
class R {
  R._();

  /// Assets for loginLogo
  /// assets/images/login/logo.png
  static const String assetsImagesLoginLogo = "assets/images/login/logo.png";

  /// Assets for tabHome
  /// assets/images/tab/home.png
  static const String assetsImagesTabHome = "assets/images/tab/home.png";
}

使用 package (Use package) #13

当通过 flutter create --template=package my_assets_package 来创建资源包时，可能会用到

flutter_assets:
  assets_path:
    - lib/assets/images/
    - lib/assets/msic/
  output_path: lib/
  filename: assets.dart
  field_prefix:
    from: libAssets
    to:
  classname: MyAsset
  package_name: my_assets_package

↓

// ignore_for_file: prefer_single_quotes
class MyAsset {
  MyAsset._();

  /// Assets for images96f775355c06519b
  /// packages/my_assets_package/lib/assets/images/雷电将军.jpeg
  static const String images96f775355c06519b = "packages/my_assets_package/lib/assets/images/雷电将军.jpeg";

  /// Assets for imagesTap
  /// packages/my_assets_package/lib/assets/images/tap.webp
  static const String imagesTap = "packages/my_assets_package/lib/assets/images/tap.webp";

  /// Assets for msicAdc
  /// packages/my_assets_package/lib/assets/msic/adc.txt
  static const String msicAdc = "packages/my_assets_package/lib/assets/msic/adc.txt";
}

此时引入时，不用每次都添加package字段

import 'package:my_assets_package/assets.dart';
// ....
Image.asset(MyAsset.images96f775355c06519b, height: 50, width: 50)
