Paul Berry d65187e6c2 Remove unnecessary ?s from web_ui. (flutter/engine#21444) ...

* Remove unnecessary `?`s from web_ui.

In https://dart-review.googlesource.com/c/sdk/+/163841, dart's flow
analysis is being changed so that an assignment like this:

    T? x = <non-nullable value>;

causes `x` to be immediately promoted to type `T`.  This exposed two
instances in which a variable was unnecessarily given a nullable type.
To avoid warnings, we need to fix these two types before
https://dart-review.googlesource.com/c/sdk/+/163841 can land.
