Test for substring in Text widget
Normally to find an entire string you can use find.text()
like this:
expect(find.text('text to find'), findsOneWidget);
What about finding a substring in a Text
widget? Say there was text of 'text to find'
, and we just wanted to check that 'to'
is a part of a Text
widget.

By using find.byWidgetPredicate
, you can specify your own validation predicate and thus check everything you want like a substring of the text.
eg :
expect(find.byWidgetPredicate((widget) {
if (widget is Text) {
final Text textWidget = widget;
if (textWidget.data != null)
return textWidget.data.contains('mySubstr');
return textWidget.textSpan.toPlainText().contains('mySubstr');
}
return false;
}), findsOneWidget);
