Let's have a look at the above code for understanding the variables that are used. Here we used the permission_handler plug-in to request the permissions and check their status:Ĭreate a dart file with the name call_page.dart, Our entire functionality will be developed on this page only, This includes showing the surface views in grid view and highlighting the speaker in the call, as well as user interaction buttons such as call end, mic mute/unmute, and camera switching: After getting the required permissions, the channel name will be passed to call_page.dart: It validates the user input and calls the _handleCameraAndMic(.) method to get the camera and mic permissions. The onJoin() method is triggered when the user clicks the join button on the home page.
If permissions are granted, then the channel name will be passed to call_page.dart:
When the user clicks the join button, the app will ask for the camera and mic permissions from the user. This page will take the channel name as input from the user. Let's create a dart file with the name home_page.dart. Create the file structure in the lib folder as shown below:Īs we know the Flutter application is initialized in the main.dart file and calls the HomePage(),which is defined in the home_page.dart file:
Add the following required dependencies in the pubspec.yaml file, and install and install those dependencies by running pub get:ģ. Create a Flutter project in your favorite IDE, and remove the boilerplate code.Ģ.
In this Nicely organized tutorial, we are going to implement a feature that highlights a speaker in a call with the Agora Flutter SDK.Īny IDE (for example, Android Studio or Visual Studio Code)ġ. When you build a video calling app with the Agora SDK, the development becomes easy. So highlighting a speaker is important for every video calling program.
We often get confused about who is speaking, which may lead to miscommunication. The Internet connection must be stable, the speaker's words must be clearly heard, and everyone should be aware of who is speaking. The tech enthusiasm led him to make a blog on Flutter named .įor a meeting or video chat to work well, several factors must come into play. Currently it seems have a little performance issue while generating WebP thumbnail by using libwebp under iOS.Satyam Parasa is a web and mobile application developer from India.
