[file_selector] "Save file" example is not web compatible. #130368
Description
Is there an existing issue for this?
- I have searched the existing issues
- I have read the guide to filing a bug
Steps to reproduce
- Compile and run the
file_selectorexampleapp in the web. - Go to the "Save File" example
- Fill in the form and click "Press to save a text file."
Expected results
In the web, a dialog prompting the user where to save the text file should be displayed, and then the file "downloaded" to the disk of the user.
Actual results
There's an error in the JS console about a missing implementation of the path_provider plugin:
Uncaught (in promise) Error: MissingPluginException(No implementation found for method getApplicationDocumentsDirectory on channel plugins.flutter.io/path_provider)

Code sample
This is the problematic bit of code:
In the web (if (kIsWeb) {), that function call should be skipped, since it's not really needed by the plugin to determine where to save a file.
