We created a fully-fledged Flutter plugin for VideoEditor SDK which is available via pub.dev as
video_editor_sdk. This wrapper library provides most customization options of our native SDK's without having to leave the Dart coding and tooling environment. Please find more information in the accompanying readme about how to integrate the plugin, the plugin's API, the available customization & configuration options in Dart as well as how to make use of native customization options beyond the options exposed to Dart.
There is also an example project which demonstrates how to use the Flutter plugin for VideoEditor SDK.
This information can also be found in our docs.
