Use case

Somewhat surprisingly, Flutter on Fuchsia does not support multi-line text editing. Only the single-line text was ever implemented in the past.
This should be fixed.

Proposal

I will modify Fuchsia-specific platform_view.cc to support multi-line text editing. This feature requires changes both in Fuchsia proper and in Flutter, which I have been rolling out in the past few weeks. (Not much work, but lots of waiting for the SDK to roll safely.)

Please assign me to this when able.
