When https://github.com/dart-lang/language/issues/1274 (Infer
non-nullability from local boolean variables) is implemented, flow
analysis will detect that code like this no longer needs to perform a
null check:
final bool contextIsValid = focus != null && focus.context != null;
...
if (contextIsValid) {
... focus! ... // Null check unnecessary
}
To avoid a build failure due to the unnecessary null check, we need to
temporarily write it in a way that we can ignore it. Once the feature
is complete and rolled into flutter, I'll remove the null check
entirely.
