flutter Unable to load asset: assets/images/lake.jpg

flutter 中加載本地資源圖片 碰到Unable to load asset: assets/images/lake.jpg 錯誤

1.在根目錄下創建assets文件夾

2.在assets下創建images文件夾,將lake.jpg圖片放入

3.在pubspec.yml 中配置

assets:
  - assets/images/lake.jpg

,如圖

4.使用方式

new Image.asset(
              'assets/images/lake.jpg',
              height: 240,
              fit: BoxFit.cover,
            ),
