[FormBuilderImagePicker] onChanged never triggered

[gilthonweapps]

Hi,

It looks like the onChanged method is never triggered. I don't see anything in the code that calls it.
I need to be able to retrieve the selected images in the onChanged.

Hi,

I also need this and saw this is not implemented. I think the fix is simple with two places to update in form_builder_image_picker.dart:

InkWell(
   onTap: () {
      var newVal = [...field.value]..remove(item);      //Add this line (about line 158)
      field.didChange(newVal);                          //Change this line (about line 158)
      widget.onChanged?.call(newVal);                   //Add this line (about line 158)
   },
...
onImageSelected: (image) {
   var newVal = [...field.value, image];                //Add this line 207
   field.didChange(newVal);                             //Change this line 207
   Navigator.of(context).pop();
   widget.onChanged?.call(newVal);                      //Add this line 207
},

thanks

Hi,

Here is what I did:

InkWell(
                              onTap: () {
                                field.didChange([...field.value]..remove(item));
                                widget.onChanged?.call(field.value);
                              },

onImageSelected: (image) {
                                  field.didChange([...field.value, image]);
                                  widget.onChanged?.call(field.value);
                                  Navigator.of(context).pop();
                                },

I think that will still give you the old value in onChanged() Or does it work correctly that way?

That'll also work.
