Description

When running my flutter app with flavors on iOS i get the following output:

 FlutterAppRequiredException: The current directory does not appear to be a Flutter application project.

 Unhandled exception:
    type 'Null' is not a subtype of type 'String' in type cast
    #0      UploadCrashlyticsSymbols.envBuildProductsDir (package:flutterfire_cli/src/commands/upload_symbols.dart:171:50)
    #1      UploadCrashlyticsSymbols.run (package:flutterfire_cli/src/commands/upload_symbols.dart:354:7)

    <asynchronous suspension>
    Command PhaseScriptExecution failed with a nonzero exit code

Steps to reproduce

1. flutter run

Expected behavior

The app should build.

Screenshots

No response

Additional context and comments

The app does build with flutterfire_cli 0.3.0-dev.18 but not with >=0.3.0-dev.19

This means you're not running from Flutter app:

 FlutterAppRequiredException: The current directory does not appear to be a Flutter application project.

This means you're running the previous version:

#3      main (file:///Users/foo/.pub-cache/hosted/pub.dev/flutterfire_cli-1.0.0/bin/flutterfire.dart:63:5)

Note flutterfire_cli-1.0.0.

It is saying the Xcode environment variable BUILT_PRODUCTS_DIR is null which is abnormal and suggests something wrong with your setup, possibly linked to FlutterAppRequiredException.

This is the script written into build phases run scripts:

[jtdLab]

Okay but why is it working with flutterfire_cli 0.3.0-dev.18 but not later versions?

[russellwheatley]

Not sure I'm afraid. Are you running the command from flutter app root?

Having the same issue, but I am using 1.1.0.

[edited] actually rolling back to 1.0.1 works for me.
