[web] Switch web-render option default to auto #23090

ferhatb · 2020-12-15T20:50:18Z

Description

Switches web-render to default to auto detect. On desktop flutter web will start using canvas kit by default, on mobile html will be used to render. Users can still override by -web-renderer=html or canvaskit.

See public doc https://docs.google.com/document/d/1aY0iU16wf_sdT7nwfpjgT-IatHNfF3slTiYHKmxcIog/edit

After this change if you encounter issues please see https://flutter.dev/docs/development/tools/web-renderers to switch to html (prior default) or canvaskit modes explicitely.

Do we also need to change something in the tool?

Predictably, there will be a significant increase in the number of questions about why text can't be displayed. Maybe we should wait until #23096 land.😃

ferhatb · 2020-12-16T17:35:45Z

@fanchou , @mariamhas : Thanks for message. Its exactly what we are doing. That fix is about to land so we are getting this ready to make sure CI and other systems are ready.
