A Flutter plugin for opening iOS and Android phone settings from an app.

Include 'app_settings' from Dart Pub.

dependencies:
  flutter:
    sdk: flutter
  app_settings: 4.1.1

Next, import 'app_settings.dart' into your dart code.

import 'package:app_settings/app_settings.dart';

The following setting options available on both iOS and Android: openAppSettings, openWIFISettings, openLocationSettings, openSecuritySettings, openBluetoothSettings, openDataRoamingSettings , openDateSettings, openDisplaySettings, openNotificationSettings, openSoundSettings, openInternalStorageSettings, openBatteryOptimizationSettings

TIP: If using Objective-C for iOS in your project, you will need to add use_frameworks! to your Runner project podfile in order to use this Swift plugin:

- target 'Runner' do
    use_frameworks!

All options open the current 'app' settings section if there are settings defined. If no current settings are defined for the app the iPhone Settings Screen will be displayed.

Each option will open and display the exact corresponding system settings screen: WIFI, Location, or Security, etc.

Using the openAppSettings option will open the current 'app' settings for the running app.

In some cases, to access directly the Bluetooth window, you will need to provide access permissions in the android/app/src/main/AndroidManifest.xml

<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.yourname.yourapp">   
	 <uses-permission android:name="android.permission.BLUETOOTH" />  
	 <uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />  
	 <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>  
 <application

Example implementation using a raised button 'onPressed' event.

Widget build(BuildContext context) {
    return Row(
        children: <Widget>[
            RaisedButton(
                onPressed: AppSettings.openLocationSettings,
                child: Text('Open Location Settings'),
            ),
        ],
    );
}
