BUGFIX Fixed some bugs on drawing PieChart (for example when we have only one section), #582,
BREAKING Border of pieChart now is hide by default (you can show it using borderData: FlBorderData(show: true).
BREAKING You cannot set 0 value on PieChartSectionData.value anymore, instead remove it from list.
BREAKING Removed fullHeightTouchLine property from LineTouchData. Now you can have a full line with following snippet:

LineTouchData(
  ...
  getTouchLineStart: (barData, index) => -double.infinity // default: from bottom,
  getTouchLineEnd: (barData, index) => double.infinity //to top,
  ...
)
