TypeError (type 'Null' is not a subtype of type 'Reference')

[17martix]

my app was crashing every time firebase_image was loading picture stating TypeError (type 'Null' is not a subtype of type 'Reference'). after looking into the code, it's the FirebaseImageObject.fromMap(Map<String, dynamic> map) method in image_object.dart causing the error because it's called with no value given to the reference key.

potential solution: make Reference variable in FirebaseImageObject nullable and it solves the problem.

I also have the same problem

======== Exception caught by image resource service ================================================
The following _TypeError was thrown resolving an image codec:
type 'Null' is not a subtype of type 'Reference'

When the exception was thrown, this was the stack: 
#0      new FirebaseImageObject.fromMap (package:firebase_image/src/image_object.dart:32:21)
#1      FirebaseImageCacheManager.get (package:firebase_image/src/cache_manager.dart:93:31)
<asynchronous suspension>
#2      FirebaseImage._fetchImage (package:firebase_image/src/firebase_image.dart:82:11)
<asynchronous suspension>
...

Any solution?

You're right, thanks👇

@difelice I don't think this is a duplicate of #37. That issue is about a warning of an unnecessary non-null assertion. This issue is about passing null to a non-null parameter at runtime and causing an exception.

I'd love to use this package but right now it's not displaying images at all. Is there a work-around for this issue, other than waiting for the PR to be merged?

[maeddin]

It still does not work. My solution was to use the fork of #45 . Thanks to @blaugold

I have the same issue and the fork of #45 fixed the issue for me, please merge it :)

I face the same issue after updating to version 1.1.0

[mattreid1]

I was unable to replicate but I'll take a look now

[mattreid1]

Ok, I merged #45 and released 1.1.1 so 🤞 that fixed it. As I was unable to replicate the problem, please let me know if it works so I can close the issue. Thanks!

[mattreid1]

Going to close this issue now but if this is still a problem then feel free to reopen it!
