Is it possible to access children/parent widgets from a given widget, in a Flutter test?

Question

I'm writing unit and integration tests for Flutter. Is it possible to access children/parent widgets from a given widget?

Answer 1

Yes, you can use find.descendant and Element.ancestorWidgetOfExactType.

Examples:

// Finds a RichText widget that a descendant (child/grand-child/etc) of a // tab widget with text "Tab 1" find.descendant(of: find.text('Tab 1'), matching: find.byType(RichText));  // Finds a parent widget of type MyParentWidget. tester.element(find.byType(MyChildWidget))   .ancestorWidgetOfExactType(MyParentWidget);
