Subject: [PATCH] Avoid passing a nullable value to Completer<nn-type>.complete
 (#1015)

This is cleanup work required to start enforcing this with static analysis, as per https://github.com/dart-lang/sdk/issues/53253.

Real quick this issue is that this code is unsafe:

```dart
void f(Completer<int> c, int? i) {
  Future<int>.value(i); // Ouch!
  c.complete(i);        // Ouch!
}
```
