Must-have Features of Video Call Apps
Video call apps have become a vital part of communication in our everyday lives. From virtual meetings, and remote learning, to catching up with family and friends, video calls offer a seamless way of connecting with people no matter where they are in the world. Here are the must-have features that every video call app should have:
1. High-Quality Video and Audio
One of the most crucial features of a video call app is the ability to deliver high-quality video and audio. A video call app should have clear and sharp visuals, as well as crisp and clear audio that will ensure that every conversation is crystal clear.
2. Multi-Platform Support
A video call app that can be used across different devices is a must-have feature. This feature ensures that users can join the call from any device they have at their disposal. A video call app that is compatible with smartphones, laptops, and tablets will ensure that users can connect with anyone, anywhere, and at any time.
3. Screen Sharing
When it comes to video call apps, one feature that has become increasingly important is the ability to share screens. It allows users to share all kinds of digital content, including documents, images, and even videos, with other participants during a call.
4. Recording
A video call app that can record meetings is a valuable feature that allows users to save and access conversations at a later time. This feature is handy for those who missed a meeting or those who want to review a previous conversation.
5. Group Calls
For anyone who needs to connect with multiple people at the same time, a video call app that supports group calls is an essential feature. Whether it’s for work-related virtual events or casual social gatherings, group calling allows users to communicate with several participants simultaneously.

final String callID;
@override
Widget build(BuildContext context) {
return ZegoUIKitPrebuiltCall(
appID: yourAppID, // Fill in the appID that you get from ZEGOCLOUD Admin Console.
appSign: yourAppSign, // Fill in the appSign that you get from ZEGOCLOUD Admin Console.
userID: 'user_id',
userName: 'user_name',
callID: callID,
// You can also use groupVideo/groupVoice/oneOnOneVoice to make more types of calls.
config: ZegoUIKitPrebuiltCallConfig.oneOnOneVideoCall()
..onOnlySelfInRoom = () => Navigator.of(context).pop(),
