问题
我遇到了一个关于我的Flutter应用程序的问题，想要在Flutter中从相册选择图片，但pickImage下面有下划线并显示了"实例成员 'pickImage' 无法使用静态访问"错误。如何修复这个错误。
这是我的代码：
class _CreateBlogState extends State<CreateBlog> {
late String authorName, title, description;
late File selectedImage;
BlogCrudMethods blogCrudMethods = new BlogCrudMethods();
Future getImage() async {
var image = await ImagePicker.pickImage(source: ImageSource.gallery);
setState(() {
selectedImage = image as File;
});
}
英文:

This is my code

你需要创建一个 ImagePicker 实例，然后使用 pickImage 方法，因为它不是静态方法。
await ImagePicker().pickImage(source: ImageSource.gallery);
英文:
You need to create a ImagePicker instance to use pickImage while it is not static method.
await ImagePicker().pickImage(source: ImageSource.gallery);
