有時會出現此錯誤，因為您需要清理構建檔案夾。嘗試flutter clean再次重建。

嘗試這個：
PickedFile pickedFile = await picker.getImage(source: ImageSource.camera);
if (pickedFile == null) {
return null;
}
Directory appDirectory = await getApplicationDocumentsDirectory();
File newImage = File(appDirectory.path 'fileName');
newImage.writeAsBytes(File(pickedFile.path).readAsBytesSync());
setState(() {
_image = newImage;
print(newImage.path ' test');
});
