11 minutes read

To present a video in Flutter from a package in Swift, you first need to integrate the video package into your Flutter project. You can do this by adding the package to your pubspec.yaml file and running flutter pub get to install it. Once the package is installed, you can use the provided widgets and classes to create and display video within your Flutter app.


To present the video, you can use the package's video player widget or customize the video player to fit your app's design. You can control the video player's playback, volume, and other properties using the package's provided methods and functions.


Additionally, you can listen for events such as when the video has finished playing or when an error occurs during playback. By handling these events, you can provide a seamless video viewing experience for your app users.


Overall, presenting a video in Flutter from a package in Swift involves integrating the package into your project, using the provided widgets and classes to create and display the video, and customizing the player to fit your app's design and functionality.
