enterText method
Give the text input widget specified by finder the focus and
enter text as if it been provided by the onscreen keyboard.
The widget specified by finder must be an EditableText or have
an EditableText descendant. For example find.byType(TextField)
or find.byType(TextFormField), or find.byType(EditableText).
To just give finder the focus without entering any text,
see showKeyboard.
Implementation
Future<void> enterText(Finder finder, String text) async {
return TestAsyncUtils.guard<void>(() async {
await showKeyboard(finder);
testTextInput.enterText(text);
await idle();
});
}
