request_permission 1.1.1

A flutter plugin for requesting android permissions, with the right string constant.

Introduction

Android

Add the permissions your app needs to the android/app/src/main/AndroidManifest.xml. Put the permissions in the manifest tag not into the application tag.

    <uses-permission android:name="android.permission.CAMERA" />
    <uses-permission android:name="android.permission.CALL_PHONE"/>
    <uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>
 <application

IOS

Currently this plugin only supports Android, if you want to you can contribute to it.

Usage

After adding the permissions, you can request them in your Flutter app in the following way:

Obtain an instance

RequestPermission requestPermission = RequestPermission.instance;

Request the permissions

RaisedButton(
    child: Text("request permissions"),
    onPressed: () {
        // 101 is the requestCode
        requestPermission.requestMultipleAndroidPermissions({
            "android.permission.CAMERA",
            "android.permission.CALL_PHONE",
            "android.permission.SYSTEM_ALERT_WINDOW"
        }, 101);
    },
),

Or request just one permission:

RaisedButton(
    child: Text("request camera permission"),
    onPressed: () {
        // 27 is the requestCode
        requestPermission.requestAndroidPermission("android.permission.CAMERA", 27);
    },
),
RaisedButton(
    child: Text("request call_phone permission"),
    onPressed: () {
        // 28 is the requestCode
        requestPermission.requestAndroidPermission("android.permission.CALL_PHONE", 28);
    },
),

Listen to the user choice

requestPermission.results.listen((event) {
   event.grantedPermissions.forEach((key, value) {
      if (value) {
        print("The permission <$value> has been granted!");
      } else {
        print("The permission <$value> has NOT been granted!");
      }
    });
});
