Does Flutter remove debug-mode code when compiling for release?

Question

I'm wondering whether it is safe to place passwords directly in the Dart code like below. Does Flutter remove the code when compiling it for release? Of course I want to make sure that the code cannot be decompiled such that the username and password can be extracted.

bool get isInDebugMode {
  bool inDebugMode = false;
  assert(inDebugMode = true);
  return inDebugMode;
}

if(inDebugMode){
  emailController.text = '[email protected]';
  passwordController.text = 'secret';
}

Answer 1

The code you provided won't be tree-shaked. As isInDebugMode isn't a constant.

Instead you can use an assert this way:

assert(() {
  emailController.text = '[email protected]';
  passwordController.text = 'secret';
  return true;
}());
