Unexpected error when compiling custom widget

[Ilry Polis]

I'm using FlutterFlow to create a custom widget with simple code to test SfCalendar, I'm using the latest version of syncfusion_flutter_datepicker: ^24.1.41.

// Automatic FlutterFlow imports

import '/flutter_flow/flutter_flow_theme.dart';

import '/flutter_flow/flutter_flow_util.dart';

import '/custom_code/widgets/index.dart'; // Imports other custom widgets

import '/flutter_flow/custom_functions.dart'; // Imports custom functions

import 'package:flutter/material.dart';

// Begin custom widget code

// DO NOT REMOVE OR MODIFY THE CODE ABOVE!

// Set your widget name, define your parameter, and then add the

// boilerplate code using the green button on the right!

import 'package:syncfusion_flutter_calendar/calendar.dart';

import 'package:syncfusion_flutter_datepicker/datepicker.dart';

class SyncfusionCalendarWidget extends StatefulWidget {

  const SyncfusionCalendarWidget({

    Key? key,

    this.width,

    this.height,

  }) : super(key: key);

  final double? width;

  final double? height;

  @override

  _SyncfusionCalendarWidgetState createState() =>

      _SyncfusionCalendarWidgetState();

}

class _SyncfusionCalendarWidgetState extends State<SyncfusionCalendarWidget> {

  @override

  Widget build(BuildContext context) {

    return Container(

      width: widget.width,

      height: widget.height,

      child: SfCalendar(

        view: CalendarView.week,

      ),

    );

  }

}

And when compiling the following error appears, please, how to fix it:

It worked when I added the dependency on version ^21.1.41.

How do I use the current version in flutterflow?

[Indumathi Ravichandran]

Hi Ilry,

As per the shared information we have checked the mentioned issue “Syncfusion Calendar Flutterflow textScaler error in the Flutter Calendar”. We have updated the Syncfusion calendar source to Flutter version 3.16 and some properties are deprecated in that version. So, we have updated source code based on the breaking changes. Due to this you are getting this issue. Please find the breaking changes in the following link. So, kindly suggest using older version of the calendar for resolving this issue.

https://docs.flutter.dev/release/breaking-changes/deprecate-textscalefactor

Please let us know if you need further assistance.

Regards,

Indumathi R
