2023-02-09 flutter命令执行流程

研究flutter xxx和dart xxx区别。

• flutter xxx 命令最终转化为：

exec 

/Volumes/xx/myshared/opt/fvm/versions/3.0.5/bin/cache/dart-sdk/bin/dart 

--disable-dart-dev 


--packages=/Volumes/xx/myshared/opt/fvm/versions/3.0.5/packages/flutter_tools/.packages  


/Volumes/xx/myshared/opt/fvm/versions/3.0.5/bin/cache/flutter_tools.snapshot 


--version

简化为

dart --disable-dart-dev --packages=.packages  flutter_tools.snapshot --version

• dart 命令转化为：

exec /Volumes/xx/myshared/opt/fvm/versions/3.0.5/bin/cache/dart-sdk/bin/dart --version

简化为
dart --version

可用：
flutter packages pub publish
flutter pub publish
dart pub publish

不可以用：
dart packages pub publish

flutter的各种命令：

0 = {map entry} "help" -> [HelpCommand]
1 = {map entry} "analyze" -> [AnalyzeCommand]
2 = {map entry} "assemble" -> [AssembleCommand]
3 = {map entry} "attach" -> [AttachCommand]
4 = {map entry} "build" -> [BuildCommand]
5 = {map entry} "channel" -> [ChannelCommand]
6 = {map entry} "clean" -> [CleanCommand]
7 = {map entry} "config" -> [ConfigCommand]
8 = {map entry} "configure" -> [ConfigCommand]
9 = {map entry} "custom-devices" -> [CustomDevicesCommand]
10 = {map entry} "create" -> [CreateCommand]
11 = {map entry} "daemon" -> [DaemonCommand]
12 = {map entry} "debug-adapter" -> [DebugAdapterCommand]
13 = {map entry} "debug_adapter" -> [DebugAdapterCommand]
14 = {map entry} "devices" -> [DevicesCommand]
15 = {map entry} "doctor" -> [DoctorCommand]
16 = {map entry} "downgrade" -> [DowngradeCommand]
17 = {map entry} "drive" -> [DriveCommand]
18 = {map entry} "driver" -> [DriveCommand]
19 = {map entry} "emulators" -> [EmulatorsCommand]
20 = {map entry} "emulator" -> [EmulatorsCommand]
21 = {map entry} "format" -> [FormatCommand]
22 = {map entry} "dartfmt" -> [FormatCommand]
23 = {map entry} "generate" -> [GenerateCommand]
24 = {map entry} "gen-l10n" -> [GenerateLocalizationsCommand]
25 = {map entry} "install" -> [InstallCommand]
26 = {map entry} "logs" -> [LogsCommand]
27 = {map entry} "make-host-app-editable" -> [MakeHostAppEditableCommand]
28 = {map entry} "pub" -> [PackagesCommand]
29 = {map entry} "packages" -> [PackagesCommand]
30 = {map entry} "precache" -> [PrecacheCommand]
31 = {map entry} "run" -> [RunCommand]
32 = {map entry} "screenshot" -> [ScreenshotCommand]
33 = {map entry} "pic" -> [ScreenshotCommand]
34 = {map entry} "bash-completion" -> [ShellCompletionCommand]
35 = {map entry} "zsh-completion" -> [ShellCompletionCommand]
36 = {map entry} "test" -> [TestCommand]
37 = {map entry} "upgrade" -> [UpgradeCommand]
38 = {map entry} "symbolize" -> [SymbolizeCommand]
39 = {map entry} "ide-config" -> [IdeConfigCommand]
40 = {map entry} "update-packages" -> [UpdatePackagesCommand]
41 = {map entry} "upgrade-packages" -> [UpdatePackagesCommand]

flutter pub publish:
command = {PackagesForwardCommand}

flutter packages pub publish:
command = {PackagesPassthroughCommand}

/Volumes/xxx/myshared/opt/fvm/current/bin/cache/dart-sdk/bin/dart

flutter 命令最终会转化为
flutter_tools.dart->
process_manager.dart

  @override
  bool canRun(dynamic executable, {String? workingDirectory}) {
    return _runSync(
      () => _delegate.canRun(executable, workingDirectory: workingDirectory),
      platform: _platform,
      failureMessage: 'Flutter failed to run "$executable"',
      posixPermissionSuggestion: 'Try running:\n'
          '  sudo chown -R \$(whoami) $executable && chmod u+rx $executable',
    );
  }
