如何使用image_picker依赖项在flutter中将图像上传到sqlite数据库

Question

Future getImage(ImageSource imageSource) async {
    var image = await ImagePicker.pickImage(source: imageSource);

    setState(() {
      _image = image;
    });
  } 

Answer 1

您可以将图像转换为字节数组并将其保存为 blob。

var image = await ImagePicker.pickImage(source: imageSource);
List<int> bytes = await image.readAsBytes();
//save to SQLite as a blob
