Fl_chart | Flutter

currently I'm facing error in Fl_chart flutter. In part of my code I insert bottomTitles: SideTitles but system shown error ["The argument type 'SideTitles' can't be assigned to the parameter type 'AxisTitles'.].

       `bottomTitles: SideTitles(
                  showTitles: true,
                  rotateAngle:
                      MediaQuery.of(context).size.width > 400 ? -45 : -90,
                  reservedSize: MediaQuery.of(context).size.width > 500
                      ? MediaQuery.of(context).size.height * 0.03
                      : MediaQuery.of(context).size.height * 0.08,
                  getTitles: (value) {
                    final hour = value.toInt();

                    final formattedHour =
                        (hour % 12 == 0) ? '12' : (hour % 12).toString();
                    final period = (hour < 12) ? 'AM' : 'PM';

                    if (formattedHour + period == previousHour) {
                      return '';
                    }
                    // Store the current title to check for duplicates in the next iteration
                    previousHour = formattedHour + period;

                    return '$formattedHour $period';
                  },
                ),`

Error Detail As Below:

I try change the SideTitles into AxisTitles system pop out another 4 Errors(refer as below), after that I search in chatGPT say that below parameters only able to use in SideTitles & advice me seek advice in library comunity.

Can anyone Help me in this issue? Thank you in advance!

Wrap your SideTitles in an AxisTitles. Try like below code. Also, check the Latest Version for some changes.

bottomTitles: AxisTitles(sideTitles: getBottomTitles),

Widget getBottomTitles(double value, TitleMeta meta) {
{
  final hour = value.toInt();

  final formattedHour = (hour % 12 == 0) ? '12' : (hour % 12).toString();
  final period = (hour < 12) ? 'AM' : 'PM';

  if (formattedHour + period == previousHour) {
    return const Text('');
  }
  // Store the current title to check for duplicates in the next iteration
  previousHour = formattedHour + period;
}
return Text('$formattedHour $period');

}

For the first one, botomTiles expects an AxisTitle, so you should wrap your SideTitle with an AxisTitle:

bottomTitles: AxisTitles(
      sideTitles: SideTitles(
        ....
      ),
    ),

And for the other errors it seems SideTitles doesn't use those parameters anymore:

  /// Determines showing or hiding this side titles
  final bool showTitles;

  /// You can override it to pass your custom widget to show in each axis value
  /// We recommend you to use [SideTitleWidget].
  final GetTitleWidgetFunction getTitlesWidget;

  /// It determines the maximum space that your titles need,
  /// (All titles will stretch using this value)
  final double reservedSize;

  /// Texts are showing with provided [interval]. If you don't provide anything,
  /// we try to find a suitable value to set as [interval] under the hood.
  final double? interval;

Check the last version of fi_chart and compare with yours
