how to set a picked image in flutter - image

Question

I tried using this for picking and Saving Image->
File imageFile;
Future getImage(int type) async {
PickedFile pickedImage = await ImagePicker().getImage(
source: type == 1 ? ImageSource.camera :
ImageSource.gallery,
imageQuality: 50
);
if (pickedImage == null) return;
File tmpFile = File(pickedImage.path);
tmpFile = await tmpFile.copy(tmpFile.path);
setState(() {
imageFile = tmpFile;
});
}
imageFile != null
? Image.file(
imageFile,
height: MediaQuery.of(context).size.height / 5,
)
: Text("Pick up the image"),
But, Image is not saving. Nothing has been Displayed. What else I need to do?

This code is very ambiguous, it's very unclear where you are calling getImage and where you are setting the image.
I suppose you are not calling getImage() properly and not sure where you are using this if (pickedImage == null) return; it might be wrong.
Anyway, here's a proper explanation it should work.
Declare your getImage method inside the Widget class.
Future<File> getImage(int type) async {
PickedFile pickedImage = await ImagePicker().getImage(
source: type == 1 ? ImageSource.camera :
ImageSource.gallery,
imageQuality: 50
);
return pickedImage;
}
Declare the File state variable in the sate class
File imageFile;
Have a Button for the selecting action of the image in your widget.
...
IconButton(
icon: Icon(Icons.gallery),
onPressed: () {}
)
...
call the getImage method and setState the result in the onPressed handler.
...
IconButton(
icon: Icon(Icons.gallery),
onPressed: () async {
final tmpFile = await getImage(1);
setState(() {
imageFile = tmpFile;
});
)
...
Display your file in a widget
imageFile != null
?Image.file(
imageFile,
height: MediaQuery.of(context).size.height / 5,
): Text("Pick up the image"),
