UI Testing if a button is enabled

Question

I want to check if a Button is disabled in my UI test.

In Android you would normally do something like this:

onView(withId(R.id.buttonId)).check(matches(not(isEnabled())));

What is the equivalent when writing a UI test for Flutter?

Answer 1

Give your Button a UniqueKey and pump the Widget and perform other test clicks, etc. Then

expect(tester.widget<FlatButton>(find.byKey(buttonKey)).enabled, isFalse);
