Flutter: codelabsのサンプルアプリのintegration testが失敗する

前提・実現したいこと

codelabsのサイトのコードを写経しながらFlutterアプリのテスト技法を学習しています。

7:integration testの最後の項目Run the testまで問題なく進んでる状況です。

以下のコマンドをターミナルで実行し、integration testを行いました。

terminal
1$ flutter drive --driver integration_test/driver.dart --target integration_test/app_test.dart --profile

######お題のアプリ
・シンプルなリスト。右のハートボタンをタップし、お気に入り登録する。
・お気に入りリストから×ボタンを押すとお気に入りを解除できる。

######テスト内容
・　Scrolling test: ListViewを上下にスクロールし、その時の挙動のパフォーマンスを確認
・　Favorites operations test : 3つのリストをお気に入り登録し、解除する

###起きている問題
2つのテストの内、Scrolling testが通らずにエラーが発生しました。
