Example

You can use the runWithPrint function to get the print output. A full test example could look like the following.

import 'package:run_with_print/run_with_print.dart';
import 'package:test/test.dart';

void main() {
  test('Check print contents', () {
    runWithPrint((logs) {
      print('test log');
      expect(logs[0], 'test log');

      print('test message');

    });

You can just wrap the test code with runWithPrint(() {}); to get the print output.
