[web] Change `--web-renderer` default from `auto` to `canvaskit` #149773

mdebbar · 2024-06-05T22:03:27Z

When --web-renderer is omitted, keep the value null until it later materializes to either canvaskit or skwasm.
No more hardcoded defaults anywhere. We use WebRendererMode.defaultForJs/defaultForWasm instead.
When in --wasm mode, the JS fallback is now canvaskit instead of auto.
Add test for defaulting to skwasm when --wasm is enabled.

) Changes the documentation of the default renderer on web. The default renderer is changing from `auto` to `canvaskit`. _This PR is mostly moving things around with no new content being added._ The PR making the code changes: flutter/flutter#149773 The issue: flutter/flutter#149826 ## Presubmit checklist - [x] This PR doesn’t contain automatically generated corrections (Grammarly or similar). - [x] This PR follows the [Google Developer Documentation Style Guidelines](https://developers.google.com/style) — for example, it doesn’t use _i.e._ or _e.g._, and it avoids _I_ and _we_ (first person). - [x] This PR uses [semantic line breaks](https://github.com/dart-lang/site-shared/blob/main/doc/writing-for-dart-and-flutter-websites.md#semantic-line-breaks) of 80 characters or fewer.

LGTM! One small nit.

@@ -964,7 +990,7 @@ void main() {
      JsCompilerConfig(optimizationLevel: 0),
      JsCompilerConfig(noFrequencyBasedMinification: true),
      JsCompilerConfig(sourceMaps: false),
-      JsCompilerConfig(renderer: WebRendererMode.canvaskit),
+      JsCompilerConfig(renderer: WebRendererMode.skwasm),


We should do WebRendererMode.auto or WebRendererMode.html here for this test, I think. JsCompilerConfig with a skwasm renderer mode, while it won't throw at this particular layer it isn't a logically valid or supported combination, so it's weird to use it in the test.

The only reason I used skwasm instead of html is because I didn't want to change it again when we remove the html renderer.

But I see what you're saying. I'll use html for now, and later remove this line entirely when there's no more html renderer.

I meant to approve earlier.
