How to use Flutter Video UIKit?

In your Flutter application, add the enx_uikit_flutter as a dependency inside your pubspec.yaml file. 

enx_uikit_flutter: ^1.0.0

Note: Add below line in for Android frameworks:

Go to project level build.gradle within all project section

Define Device Permissions

enx_uikit_flutter requires camera and microphone permission to start video call.

For Android: Open the AndroidManifest.xml file and add the required device permissions to the file. 

<uses-permission android:name="android.permission.CAMERA" /> 
<uses-permission android:name="android.permission.INTERNET"/> 
<uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" /> 
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" /> 
<uses-permission android:name="android.permission.RECORD_AUDIO" /> 
<uses-permission android:name="android.permission.BLUETOOTH" /> 
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" /> 
<uses-permission android:name="android.permission.WAKE_LOCK" /> 

For iOS: Open info.plist and add:

  • Privacy: Microphone Usage Description, and add a note in the Value column.
  • Privacy: Camera Usage Description, and add a note in the Value column.

How to get Camera and mic permission in Flutter?

Create common method for permission: 

Future<bool> handlePermissionsForCall(BuildContext context) async {
  Map<Permission, PermissionStatus> statuses = await [


   if (statuses[Permission.camera]!.isPermanentlyDenied) {
    showCustomDialog(context, "Permission Required",
        "Camera Permission Required for Video Call", () {
    return false;
  } else if (statuses[Permission.microphone]!.isPermanentlyDenied) {
    showCustomDialog(context, "Permission Required",
        "Microphone Permission Required for Video Call", () {
    return false;

  if (statuses[Permission.camera]!.isDenied) {
    return false;
  } else if (statuses[Permission.microphone]!.isDenied) {
    return false;
  return true;

void showCustomDialog(BuildContext context, String title, String message,
    Function okPressed) async {
    context: context,
    barrierDismissible: false,
    builder: (BuildContext context) {
      // return object of type Dialog

      return AlertDialog(
        shape: const RoundedRectangleBorder(
            borderRadius: BorderRadius.all(Radius.circular(10.0))),
        title: Text(
        content:  Text(
        actions: <Widget>[
             const Text("OK"),
            onPressed: okPressed(),

Call above method as per your requirements after creating token:

bool isPermissionGranted = await handlePermissionsForCall(context);

Follow next steps if Device Permission is granted.



To use the Enx_UIKit_Flutter Framework user must have the following:

Code a little

  • Step#1: Go to your class and import the enx_uikit_flutter 
import 'package:enx_uikit_flutter/enx_uikit_flutter.dart'; 
  • Step#2: Initiate EnxVideoView Class: You are to pass a valid Token and handle callback.
// embedUrl is optional, used to import settings of Low Code
EnxVideoView(token: token,  embedUrl: "Low Code Host URL”,
connectError: (Map<dynamic, dynamic> map) {
		`//Here is the reason,  will carry information about cause of error
		`print('connectError' + jsonEncode(map));	
	disconnect: (Map<dynamic, dynamic> map) {
		//Here is the reason,  will carry information about cause of disconnection
		print('disconnect' + jsonEncode(map));

UI Customization

To Customize Bottom Option:

var setting = EnxSetting.instance;

To customize Top Option:

var setting = EnxSetting.instance;

To customize Participant List: Use configureParticipantList() method to add different options against each participants in Participant List. Refer example below:

var setting = EnxSetting.instance; 

// Show disconnect option against each participant

// Show private chat option against each participant

To create extra Button: Use createExtraButton() method to create a list of buttons to use with your own style.

var setting = EnxSetting.instance; 
		onPressed: () async {
		child: Container( 
			padding: const EdgeInsets.all(1.0), 
			decoration: const BoxDecoration(
				shape: BoxShape.circle, 
				color: Colors.blue), 
			child: const Icon( 
				color: Colors.white, 
				size: 20)
