debugUpdate method
void
debugUpdate()
A test utility to test the behavior of your initState/update method.
The first time debugUpdate is called, this will call initState + update. Further calls will only call update.
While inside update, read will be disabled as it would be in production.
Implementation
void debugUpdate() {
assert(() {
if (!_debugDidInitState) {
_debugDidInitState = true;
initState();
}
final locator = read;
read = <T>() => throw StateError('Cannot use `read` inside `update`');
try {
update(locator);
} finally {
read = locator;
}
return true;
}(), '');
}
