FlSimpleErrorPainter class

The default implementation of FlSpotErrorRangePainter

It draws a simple and common error indicator for the error range of a point in our axis based charts such as LineChart and BarChart

You can see how does it look in the example app

You can customize the lines using lineColor, lineWidth, capLength,

You can customize the alignment of the error lines using crossAlignment

capLength → double: The length of the cap of the error lines
final
crossAlignment → double: The alignment of the error lines, it should be between -1 (start) and 1 (end)
final
errorTextDirection → TextDirection: The direction of the error texts
final
errorTextStyle → TextStyle: The style of the error texts
final
hashCode → int: The hash code for this object.
