Introduction #
Flutter package to be able to get the args passed to an Android or iOS application. This plugin currently only supports Android and iOS as most other platforms provide the args to the main function directly.

Usage #
import 'package:flutter/material.dart';
import 'package:launch_args/launch_args.dart';

Future<void> main(List<String> args) async {
WidgetsFlutterBinding.ensureInitialized();
args = args?.isNotEmpty == true ? args : (await LaunchArgs.args);

runApp(MyApp(args: args));
}

Note: The arg names on android will be prefexed with -- to make it compatible with the options from the args package as Android always uses key / value pairs.
iOS #
ios-deploy
$FLUTTER_HOME/bin/cache/artifacts/ios-deploy/ios-deploy --id $DEVICE_ID \
--bundle build/ios/iphoneos/Runner.app \
--debug \
--args [arg name] [arg value] [arg name2] [arg value2] ...
