flutter image加载本地图片

• 项目中创建assets文件夹，图片拖放到文件夹中。
• pubspect.yaml文件中，添加图片路径：

# The following section is specific to Flutter.
flutter:

  # The following line ensures that the Material Icons font is
  # included with your application, so that you can use the icons in
  # the material Icons class.
  uses-material-design: true

  # To add assets to your application, add an assets section, like this:
  assets:
     - assets/1.png
     - assets/2.png

注意： assets:前不要有空格，否则报错。

• 引用本地图片：

new Image.asset('assets/1.png'),
new Image.asset('assets/2.png'),
