env variables are not passed to dart vm

[GioPan04]

The env variables defined in the host system are not passed to the dartvm.

Example:

void main() {
  final String user = Platform.environment['USER'];
  print(user);
}

This will output null.

Since you can't build a bundle with --dart-define, there is any way to pass a env variable to the flutter app?

I can not confirm this behavior - tested inside my flutter app

    print(Platform.resolvedExecutable);
    print(Platform.environment['PATH']);

works fine

flutter: /usr/local/bin/flutter-pi
flutter: /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/games:/usr/games:/opt/dart-sdk/bin

From a first look it seems like Platform.environment internally delegates to the dart runtime, which will in turn just copy everything from from environ. Don't know why it shouldn't work, the implementation is exactly the same for linux desktop and for android too, but I'll test it

EDIT: Seems like it works fine for me using debug & release mode with and without sudo. Can you try iterating through Platform.environment and printing out the contents to see if maybe some other variables are defined for you?

Okay, I'll test this

Platform.environment['varname'] and String.fromEnvironment('varname') both worked for me in debug mode.
In release mode only Platform.environment['varname'] worked.
