| # `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`](../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`](spring_animation/README.md). |
| |
| - Code that is licensed separately from the rest of the Flutter repository. |
| For example, see [`third_party/txt`](txt/). |
| |
| When adding a new _externally_ sourced third-party library, update `.gitignore`: |
| |
| ```diff |
| # Ignores all third_party/ directories except for the ones we want to track. |
| |
| + !{folder_name}/ |
| ``` |
