+* **FEATURE** (by @imaNNeo) Add error range feature in our axis-based charts. You can set `xError` and `yError` in the [FlSpot](https://github.com/imaNNeo/fl_chart/blob/main/repo_files/documentations/base_chart.md#flspot) or `toYErrorRange` in [BarChartRodData](https://github.com/imaNNeo/fl_chart/blob/main/repo_files/documentations/bar_chart.md#barchartroddata). Also we have `errorIndicatorData` property in our [LineChartData](https://github.com/imaNNeo/fl_chart/blob/main/repo_files/documentations/line_chart.md#linechartdata), [BarChartData](https://github.com/imaNNeo/fl_chart/blob/main/repo_files/documentations/bar_chart.md#barchartdata) and [ScatterChartData](https://github.com/imaNNeo/fl_chart/blob/main/repo_files/documentations/scatter_chart.md#scatterchartdata) that is responsible to render the error bars. You can take a look at the [LineChartSample 13](https://github.com/imaNNeo/fl_chart/blob/main/example/lib/presentation/samples/line/line_chart_sample13.dart) and [BarChartSample 8](https://github.com/imaNNeo/fl_chart/blob/main/example/lib/presentation/samples/bar/bar_chart_sample8.dart) in our [sample app](https://app.flchart.dev), #1483
