Skwasm heavy #166619

eyebrowsoffire · 2025-04-05T00:09:56Z

This produces a build of Skwasm that works on Firefox and Safari. This means we use SkAnimatedImage for animated gifs and webps and use builtin ICU data in Skia.

I have unit test suites for Safari and Firefox with dart2wasm and both ui and engine test sets. However, there are a few issues with running these on CI:

Safari+dart2wasm doesn't work yet until the CI bots are upgraded to macOS 15, so these have been disabled on CI for now (but you can run the unit test suite locally).
Firefox+ui doesn't work because our Linux bots have no GPU and therefore no WebGL2 support, so that one is disabled. Firefox+dart2wasm with the engine suite is enabled on CI though.

I did make some changes to the host page for our unit test harness so that Safari actually works though. Even though we're not running on CI, you can still run locally if you have macOS 15.

This is a reland of flutter#164748, which was reverted here: flutter#165350 It was reverted due to some issues in the flutter packages roller: flutter#165347 The unit test in flutter/packages was modified to be more deterministic and less affected by minor timing differences: flutter/packages#8920 So this is basically being relanded without any significant changes, since the downstream tests have been fixed.

…are broken.
