如何修复 ImagePicker 取消按钮上的“NoSuchMethodError：getter 'path' was called on null”？

Question

伙计们，我正在使用 ImagePicker 插件访问我的应用程序中的图像，但是如果我决定取消它，我会收到此错误 NoSuchMethodError: The getter 'path' was called on null。关于如何修复它的任何想法？

这是我的ImagePicker：

FlatButton(
          onPressed: () async {
            final PickedFile file =
                await picker.getImage(source: ImageSource.camera);
            editImage(file.path);
          },
          child: Text('Câmera'),
        ),

修复：

FlatButton(
          onPressed: () async {
            final PickedFile file =
                await picker.getImage(source: ImageSource.camera);
            if (file != null) {
              editImage(file.path);
            }
          },
          child: Text('Câmera'),
        ),
