[syncfusion_flutter_charts] When tapping on an external label with a large description on Android, the tooltip is not displayed

[mdmota]

Bug description

syncfusion_flutter_charts: ^25.1.41+2

I created a circular chart and some outside labels are large and do not appear completely on the screen. When you tap on the label, the tooltip is displayed on iOS and on the Anroid emulator version 13. On a physical cell phone with Android 14, when you tap on the label, it is not displayed on the tooltip.

Steps to reproduce

Create a chart with a large label and tap on it on Android 14. The label has 'text...' but when tapped it does not display the full text

Code sample

SfCircularChart _buildSmartLabelPieChart() {
    return SfCircularChart(
      title: ChartTitle(text:tittle, textStyle: TextStyle(fontSize: 14, fontWeight: FontWeight.w600)),
      series: _gettSmartLabelPieSeries(),
      tooltipBehavior: TooltipBehavior(enable: true, header: '', format: 'point.x', decimalPlaces: 2),
    );
  }

  /// Returns the pie series with smart data labels.
  List<PieSeries<ChartData, String>> _gettSmartLabelPieSeries() {
    return <PieSeries<ChartData, String>>[
      PieSeries<ChartData, String>(
          name: title,
          dataSource: listData,
          xValueMapper: (ChartDatadata, _) => data.x as String,
          yValueMapper: (ChartDatadata, _) => data.y,
          dataLabelMapper: (ChartDatadata, _) =>  data.x + ' ${data.xValue}',
          radius: '60%',
          dataLabelSettings: DataLabelSettings(
              margin: EdgeInsets.zero,
              isVisible: true,
              labelPosition: ChartDataLabelPosition.outside,
              connectorLineSettings: const ConnectorLineSettings(
                  type: ConnectorType.curve, length: '20%'),
              labelIntersectAction: LabelIntersectAction.shift))
    ];
  }
