flutter/third_party

This directory contains third-party code that is a combination of:

  • Code that is vendored into the Flutter repository, from an external source. For example, we might have third_party/glfw, which contains the GLFW library, vendored from an external repository.

    💡 TIP: See DEPS for where these sources are declared.

  • Code that originates from another repository, but is copied (sometimes with alterations) into the Flutter repository. For an example, see third_party/spring_animation.

  • Code that is licensed separately from the rest of the Flutter repository. For example, see third_party/txt.

When adding a new externally sourced third-party library, update .gitignore:

# Ignores all third_party/ directories except for the ones we want to track.

+ !{folder_name}/
