句读App 的 Flutter 版本

json生成实体的步骤:

1.json生成实体: https://caijinglong.github.io/json2dart/index_ch.html
2.json 生产.g.dart的命令: flutter packages pub run build_runner build

问题总结:

1,/Users/.../Library/Flutter/flutter/bin/flutter --no-color packages get Waiting for another flutter command to release the startup lock... 解决方法:

1：关闭 AndroidStudio

2：CTRL+ALT+DEL 关闭所有 dart进程和android进程,注意adb这个别忘了关

3：打开 flutter 安装目录如：...\flutter\flutter\bin\cache,删除里面的 lockfile

4：打开 AndroidStudio 先点击下面的 Invalidate 再打开此窗口点击 Just Restart

2,错误如下:

[INFO] Checking for unexpected pre-existing outputs.... [INFO] Found 14 declared outputs which already exist on disk. This is likely because the.dart_tool/build folder was deleted, or you are submitting generated files to your source repository. [SEVERE] Conflicting outputs were detected and the build is unable to prompt for permission to remove them. These outputs must be removed manually or the build can be run with --delete-conflicting-o utputs. The outputs are: lib/data/http/rsp/BaseRsp.g.dart

[INFO] Generating build script... [INFO] Generating build script completed, took 246ms [SEVERE] Nothing can be built, yet a build was requested. pub finished with exit code 78

解决方法:

//清除之前生成的文件，如果直接运行下面的不行。可以先尝试运行这个 flutter packages pub run build_runner clean //可以直接运行这个 flutter packages pub run build_runner build --delete-conflicting-outputs
