setSurfaceSize method Null safety
- Size? size
Artificially changes the surface size to size
on the Widget binding,
then flushes microtasks.
Set to null to use the default surface size.
Implementation
Future<void> setSurfaceSize(Size? size) {
return TestAsyncUtils.guard<void>(() async {
assert(inTest);
if (_surfaceSize == size) {
return;
}
_surfaceSize = size;
handleMetricsChanged();
});
}
