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));
}

Passing Args

Android

adb

adb -s $DEVICE_ID shell am start \
  -n $ANDROID_PACKAGE/$ANDROID_ACTIVITY \
  -ez [arg name] [value] \
  -ez [arg name2] [value 2] \
  ...

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] ...
