FormBuilderCheckboxList error onTap : UnmodifiableListBase.add

[dzluppin]

Hey, this plugin is actually a life saver. But I have a problem when using FormBuilderCheckboxList inside FutureBuilder. All checkbox not work when clicked.

Here's my code :

FutureBuilder(
builder: (BuildContext context, AsyncSnapshot<List> snapshot) {
if (snapshot.hasData) {
return FormBuilderCheckboxList(
attribute: 'artCategory',
leadingInput: true,
options: snapshot.data
.where((test) => test.tipe)
.map((dt) => FormBuilderFieldOption(value: dt.id.id, label: dt.title))
.toList(),
);
} else if (snapshot.hasError) {
return Center(
child: Text(snapshot.error),
);
}
return Center(
child: ListTile(
leading: CircularProgressIndicator(),
title: Text('Loading Category...'),
),
);
},
future: _bloc.categoryByARTType(widget.form.tipe, widget.form.objectObserv),
)

Then, when i click some checkbox, flutter throw this error :

flutter: Unsupported operation: Cannot add to an unmodifiable list flutter: Handler: "onTap" Recognizer: TapGestureRecognizer#3f16e flutter: #0 UnmodifiableListBase.add (dart:_internal/list.dart:114:5) #1 _FormBuilderCheckboxListState._checkbox.<anonymous closure> (package:flutter_form_builder/src/fields/form_builder_checkbox_list.dart:78:27)

• ps : I don't know how to write code in issue submission so i used quote instead. Sorry.
