    1.安装

    使用当前包作为依赖库

    1. 依赖此库

    在文件 'pubspec.yaml' 中添加

    [图片上传失败...(image-a91624-1586774582991)]

    
    dependencies:
    
      ai_progress: ^version
    
    

    或者以下方式依赖

    dependencies:
    
      # ai_progress package.
      ai_progress:
        git:
          url: https://github.com/pdliuw/ai_progress.git
    
    

    2. 安装此库

    你可以通过下面的命令行来安装此库

    
    $ flutter pub get
    
    
    

    你也可以通过项目开发工具通过可视化操作来执行上述步骤

    3. 导入此库

    现在,在你的Dart编辑代码中,你可以使用:

    
    import 'package:ai_progress/ai_progress.dart';
    
    

    2.使用
