flutter - 如何复制图像的路径并将其存储在其中？错误：- 方法副本未定义为类型“PickedFile”

Question

这是使用复制功能时的错误。如何保存从相机点击的图像？

Future _takePicture() async {
    final imageFile = await ImagePicker().getImage(
      source: ImageSource.camera,
      maxHeight: 600,
    );
    setState(() {
      _storedImage = File(imageFile.path);
    });
    final appDir = await syspaths.getApplicationDocumentsDirectory();
    final fileName = path.basename(imageFile.path);
    final savedImage = await imageFile.copy('${appDir.path}/$fileName');
  }

Answer 1

你应该复制_storedImage而不是imageFile

imageFile类型是PickedFile和没有copy方法

Future _takePicture() async {
        final imageFile = await ImagePicker().getImage(
          source: ImageSource.camera,
          maxHeight: 600,
        );
        setState(() {
          _storedImage = File(imageFile.path);
        });
        final appDir = await syspaths.getApplicationDocumentsDirectory();
        final fileName = path.basename(imageFile.path);
        final savedImage = await _storedImage.copy('${appDir.path}/$fileName');
      }
