Build failed: Could not resolve Gradle dependencies (video_thumbnail)

When trying to build my Flutter project with the video_thumbnail plugin, the build fails because Gradle cannot resolve required dependencies.

FAILURE: Build failed with an exception.

A problem occurred configuring project ':video_thumbnail'.
