runDartOrFlutterCommand static method

Future runDartOrFlutterCommand(String forDirectory, { List<String> args = const [], StdoutSession? stdoutSession, bool forceUseFlutterTool = false, })

runs the dart or flutter command with the given args. The decision which command to run is taken from the pubspec.yaml file in forDirectory This command determines which tool to use based on the pubspec.yaml file. If forceUseFlutterTool is given then this value will be used to determine which tool to use. true means Flutter, false means Dart
