0.20.0-nullsafety1 #

[BREAKING] We have migrated our project to null-safety. You may need to change your source-code to compile. check migration guide.

[Improvement] Show tooltips on mouse hover on Web, and Desktop.

0.12.2 #

[Improvement] Added badgeWidget, and badgePositionPercentageOffset in each PieChartSectionData to provide a widget to show in the chart, see this sample, #443. Providing a widget is an important step in our library, if it works perfectly, we will aplly this solution on other parts. Then I appreciate any feedback.
