fl_chart fails in flutterflow

[yuvzohar]

I'm trying to integrate inside my FlutterfFow project the fl_chart examples but it keeps failing with an error message related to the 'tooltipBgColor' (attached screenshot)

I'm using the latest code taken from https://github.com/imaNNeo/fl_chart/
dependency: fl_chart: ^0.68.0
Also followed the instructions and examples inside https://pub.dev/packages/fl_chart

The steps I've taken:

1- Created a custom widget named FLChartBarWidget (same as the class name in my code).

2- Copied the code example of the bar chart taken from here:
https://github.com/imaNNeo/fl_chart/blob/main/example/lib/presentation/samples/bar/bar_chart_sample1.dart

3- The original code example contains 2 url links which failed to be compiled in FF:

import 'package:fl_chart_app/presentation/resources/app_resources.dart';
import 'package:fl_chart_app/util/extensions/color_extensions.dart';

So I've copied their content inside the bottom of my custom widget code (see below).

4- The code compiled successfully inside the custom code section

5- Integrated my FLChartBarWidget component inside one of my project pages and everything seemed to work properly (the Mingguan widget at the bottom):

6- Running the project in test or run mode crashes with the mentioned error message (attached)

What have you tried so far?

1- I've opened the developer tools in my browser to see if I can get more information but this did'nt really help

2- I've tried running with both local FF mac desktop app and FF web app

3- Running it as a clean Flutter code in Android Studio is working fine,, the problem is only with FF.

• I've noticed that FF is not using the latest Flutter and Dart SDKs.

• Maybe this would be the reason for this?

• I also couldn't find a way to force FF using the latest. Is it possible?

The following is the code I'm using for my custom widget:
