Flutter keyboard_actions widget area scrolling is not working - flutter

Question

My task was to add button Done to text keyboard which hides keyboard after CupertinoTextField is filled with value. I used keyboard_actions lib and it worked fine, but the area of FormKeyboardActions() widget became unscrollable - scrolling is broken after my implementation of
keyboard_actions lib.
I tried to add directly CupertinoTextField to FormKeyboardActions() as a child, but it is also not working.
The code of parent PageTemplate widget:
#override
Widget build(BuildContext context) {
return GestureDetector(
onTap: () {
FocusScope.of(context).unfocus();
},
child: Scaffold(
body: FormKeyboardActions(
child: SafeArea( //child
child: Padding(
padding: DesignPadding.V16__X,
child: ListView(
shrinkWrap: true,
children: this.children
),
),
),
),
floatingActionButton: Padding(
padding: const EdgeInsets.symmetric(horizontal: 20.0, vertical: 8),
child: this.floatingActionButton,
),
floatingActionButtonLocation: FloatingActionButtonLocation.centerFloat,
),
);
}
The widget with CupertinoTextField:
class _ProductEditCommentState extends State<ProductEditComment> {
final FocusNode focusNode = FocusNode(skipTraversal: true);
KeyboardActionsConfig _buildConfig(BuildContext context) {
return KeyboardActionsConfig(
keyboardActionsPlatform: KeyboardActionsPlatform.ALL,
keyboardBarColor: Colors.grey[200],
nextFocus: false,
actions: [
KeyboardAction(
focusNode: focusNode,
closeWidget: Padding(
padding: DesignPadding.V8__X,
child: Text(
"Done",
style: TextStyle(
color: DesignColors.BLACK,
fontSize: DesignFonts.FONT_SIZE__16,
fontFamily: DesignFonts.FONT_FAMILY__MEDIUM,
),
),
),
),
],
);
}
#override
void initState() {
FormKeyboardActions.setKeyboardActions(context, _buildConfig(context));
super.initState();
}
#override
void dispose() {
super.dispose();
}
#override
Widget build(BuildContext context) {
ProductEditBloc bloc = BlocProvider.of(context);
return SingleChildScrollView(
child: CupertinoTextField(
focusNode: focusNode,
maxLines: null,
onChanged: this.widget.onChanged,
controller: this.widget.controller,
keyboardType: TextInputType.multiline,
decoration: BoxDecoration(border: null),
textCapitalization: TextCapitalization.sentences,
placeholder: bloc.productComment == null || bloc.productComment.isEmpty
? "Добавить заметку"
: bloc.productComment,
placeholderStyle: TextStyle(
color: DesignColors.GREY_CHROME,
fontSize: DesignFonts.FONT_SIZE__14,
fontFamily: DesignFonts.FONT_FAMILY__REGULAR),
style: TextStyle(
color: DesignColors.GREY_COAL,
fontSize: DesignFonts.FONT_SIZE__14,
fontFamily: DesignFonts.FONT_FAMILY__REGULAR),
padding: EdgeInsets.only(
left: DesignPadding.V10,
top: DesignPadding.V14,
bottom: DesignPadding.V20,
),
),
);
}
}
The implementation of ProductEditComment widget:
#override
Widget build(BuildContext context) {
return BlocProvider(
bloc: bloc,
child: PageTemplate(
children: <Widget>[
Heading(
title: "Заметка",
style: DesignFonts.STYLE_TITLE,
),
StreamBuilder<String>(
stream: bloc.outComment,
initialData: this.widget.product?.comment,
builder: (context, snapshot) {
return ProductEditComment(
name: snapshot.data,
onChanged: bloc.setComment,
controller: bloc.commentController,
);
}),
]
)
