FakeKeyValueStorage class
In-memory KeyValueStorage double for widget and unit tests.
Behaves like the real storage without any platform channel:
- values live in the public data map,
- writes do not notify stream (mirroring the real self-notification suppression),
- simulateExternalChange plays the role of another engine or native code writing to the store.
Install it by overriding the singleton:
final storage = FakeKeyValueStorage();
KeyValueStorage.instance = storage;
