Variable `FlutterPubCachePath` provides an empty directory

[Zazo032]

Pipeline:

  - task: Cache@2
    displayName: 'Cache Flutter'
    inputs:
      cacheHitVar: FLUTTER_CACHED
      key: 'flutter | stable | $(Agent.OS)'
      path: $(Agent.ToolsDirectory)/flutter

  - task: FlutterEnv@0
    condition: eq(variables.FLUTTER_CACHED, 'true')
    displayName: 'Setup Flutter'
    inputs:
      customPath: '$(Agent.ToolsDirectory)/flutter'
      pathType: 'customPath'

  - task: FlutterInstall@0
    condition: eq(variables.FLUTTER_CACHED, 'false')
    displayName: 'Install Flutter'
    inputs:
      channel: 'stable'
      mode: 'auto'
      version: 'latest'

  - task: CmdLine@2
    displayName: 'Dart: Pub get'
    inputs:
      failOnStderr: true
      script: 'dart pub get'

  - task: CmdLine@2
    displayName: 'Pub cache path (task)'
    inputs:
      script: 'echo $(FlutterPubCachePath)'

  - task: CmdLine@2
    displayName: 'Pub cache files (task)'
    inputs:
      script: 'ls -a $(FlutterPubCachePath)'

The output of Pub cache path (task):

/opt/hostedtoolcache/flutter/.pub-cache

The output of Pub cache files (task):

ls: cannot access '/opt/hostedtoolcache/flutter/.pub-cache': No such file or directory
##[error]Bash exited with code '2'.

Seems like the returned path from FlutterPubCachePath is wrong or dart pub get is not saving the packages in that directory

Hi, the issue is on latest versions of Flutter (that directory doesn't exists)

You can use these two already available commands

• $(DartToolPath)/dart pub cache pub-cache.
• OR, $(FlutterToolPath)/flutter pub get

Both of these paths provide you with pub commands so you don't need the FlutterPubCachePath. This isn't an issue from this extension but how the Flutter evolved and upgraded over the years.

Close this issue once you verify the above solution.
