Also add the following snippet in app-level build.gradle <project root>/android/app/build.gradle:
// Build the plugin project with warnings enabled. This is here rather than
// in the plugin itself to avoid breaking clients that have different
// warnings (e.g., deprecation warnings from a newer SDK than this project
// builds with).
gradle.projectsEvaluated {
project(":video_player_android_mux") {
tasks.withType(JavaCompile) {
options.compilerArgs << "-Xlint:all" << "-Werror"

// Workaround for several warnings when building
// that the above turns into errors, coming from
// org.checkerframework.checker.nullness.qual and
// com.google.errorprone.annotations:
//
// warning: Cannot find annotation method 'value()' in type
// 'EnsuresNonNull': class file for
// org.checkerframework.checker.nullness.qual.EnsuresNonNull not found
//
// warning: Cannot find annotation method 'replacement()' in type
// 'InlineMe': class file for
// com.google.errorprone.annotations.InlineMe not found
//
// The dependency version are taken from:
// https://github.com/google/ExoPlayer/blob/r2.18.1/constants.gradle
//
// For future reference the dependencies are excluded here:

void main() => runApp(const VideoApp());

/// Stateful widget to fetch and then display video content.

Usage #
The following section contains usage information that goes beyond what is included in the
documentation in order to give a more elaborate overview of the API.
This is not complete as of now. You can contribute to this section by opening a pull request.
Playback speed #
You can set the playback speed on your _controller (instance of VideoPlayerController) by
calling _controller.setPlaybackSpeed. setPlaybackSpeed takes a double speed value indicating
the rate of playback for your video.
For example, when given a value of 2.0, your video will play at 2x the regular playback speed
and so on.
To learn about playback speed limitations, see the setPlaybackSpeed method documentation.
Furthermore, see the example app for an example playback speed implementation.
