flutter imagePicker库不调用Aysnc等待功能？

我对ImagePicker库和异步 - WAIT函数有问题。因此，从我的家庭视图中，我调用了一个函数，这是

onPressed: () {
controller.pickImage();
},

我使用ImagePicker的函数

  void pickImage() async {
    print("call on click add photo icon");
    final ImagePicker _picker = ImagePicker();
    final XFile? pickedImage =
        await _picker.pickImage(source: ImageSource.gallery);
    print(
        'picked image filled with an image from gallery'); //This doesn't print at all

    if (pickedImage != null) {
      Get.snackbar('Profile Picture',
          'You have successfully selected your profile picture!');

      _pickedImage = Rx<File>(File(pickedImage.path));
    }
  }

，所以我试图通过此打印进行调试，所以我得到了第一个打印一部分，我不知道实际上是什么问题，看起来等待部分从未执行过。

I have an issue with the ImagePicker library and async-await function. So on my home view, I invoke a function, here is the code

onPressed: () {
controller.pickImage();
},

Here is my function with ImagePicker

  void pickImage() async {
    print("call on click add photo icon");
    final ImagePicker _picker = ImagePicker();
    final XFile? pickedImage =
        await _picker.pickImage(source: ImageSource.gallery);
    print(
        'picked image filled with an image from gallery'); //This doesn't print at all

    if (pickedImage != null) {
      Get.snackbar('Profile Picture',
          'You have successfully selected your profile picture!');

      _pickedImage = Rx<File>(File(pickedImage.path));
    }
  }

So I tried to debug with this printing, so I get the first print but after that nothing, it looks like I'm losing that await part, I don't know what actually is the problem, it looks await part is never executed.

尝试这样。

Future pickImage() async {
print("call on click add photo icon");
ImagePicker _picker = ImagePicker();
XFile pickedImage =
    await _picker.pickImage(source: ImageSource.gallery);

print(
    'picked image filled with an image from gallery'); //This doesn't print at all

if (pickedImage != null) {
  Get.snackbar('Profile Picture',
      'You have successfully selected your profile picture!');

  _pickedImage = File(pickedImage.path);
}}

Try like this.

Future pickImage() async {
print("call on click add photo icon");
ImagePicker _picker = ImagePicker();
XFile pickedImage =
    await _picker.pickImage(source: ImageSource.gallery);

print(
    'picked image filled with an image from gallery'); //This doesn't print at all

if (pickedImage != null) {
  Get.snackbar('Profile Picture',
      'You have successfully selected your profile picture!');

  _pickedImage = File(pickedImage.path);
}}
