Flutter图像拾取器未提供图像路径

Question

我正试图使用图像选择器在flutter中使用相机获取图像，但我收到了一个错误

lib/Screen/AllDocuments.dart:15:3: Error: 'File' isn't a type.
File _image;

我也试过投，但它仍然不起作用

File _image;
final picker = ImagePicker();
Future getImage() async {
final pickedFile = await picker.getImage(source: ImageSource.camera);
setState(() {
_image = File(pickedFile);
});
}

如何修复这个错误

Answer 1

您必须在pickedFile上调用.path方法。请在此处查看此文档=>图像选取器

使用此：

File _image;
final picker = ImagePicker();
Future getImage() async {
final pickedFile = await picker.getImage(source: ImageSource.camera);
setState(() {
_image = File(pickedFile.path);
});
}
