Contributing to Flutter SVG

Found a bug? Want an enhancement? Feel free to submit a pull request for it!

Creating a Pull Request

Contributions are welcome in this repo. Before submitting, please ensure that your request will pass CI:

flutter format .
flutter analyze .
flutter test

If you're adding a feature that impacts rendering, please add an SVG asset to the assets/ folder, and then run flutter test tool/gen_golden.dart to update the golden image files. Note that this has not been tested in Windows platforms. If you're unable to run it, let me know and I'll work with you to update the goldens.

Passing the golden tests is critical to ensure backward compatibility, and that your code has not unintentionally broken a previously working feature. While sometimes such changes are necessary to fix a broken rendering method, they should not be introduced without care.

If you're fixing a bug, please make sure to include some tests that fail before applying your fix and now succeed. This might be a regular Dart unit test, or it could be a SVG in the assets/ folder and a corresponding PNG in goldens/ that now renders correctly because of your fix.

For the PR to be incorporated into the package, it must be compatible with the the latest beta channel for Flutter (or, the latest stable/mainline release). If it someday becomes possible to conditionally pre-process the Dart code based on Flutter/Dart version, this can be relaxed.

Opening an issue

If you've got an issue and you're not able to fix it yourself, or you're looking for feedback before doing any coding work for a PR, feel free to open an issue about it.

If the issue is related to rendering or a specific SVG feature, be sure to include at least one sample SVG. The smaller/simpler the example, the better.

If the issue is related to architecture/project structure/coding standards, consider including some kind of example of what you're trying to achieve. For example, instead of saying

This project should use Design Pattern X to solve Problem Y! I love pattern X and when we used it on Project Z it made everything better.

consider

Here's an example of implementing this feature using Deisgn Pattern X. This memory/time benchmark shows that it makes rendering perform 10% faster on Phone Model W....

or

It's very difficult to implement feature A in the current codebase. Applying Pattern X could help solve this, as in the following example....

which will be received better.
