Common Charting library

pub package

Common componnets for charting libraries.


  • SelectionModelConfig's listener parameter has been renamed to "changeListener". This is a breaking change. Please rename any existing uses of the "listener" parameter to "changeListener". This was named in order to add an additional listener "updateListener" that listens to any update requests, regardless if the selection model has changed.
  • CartesianChart's method getMeasureAxis(String axisId) has been changed to getMeasureAxis({String axisId) so that getting the primary measure axis will not need passing any id that does not match the secondary measure axis id. This affects users implementing custom behaviors using the existing method.


  • Declare compatibility with Dart 2.
  • BasicNumericTickFormatterSpec now takes in a callback instead of NumberFormat as the default constructor. Use named constructor withNumberFormat instead. This is a breaking change.
  • BarRendererConfig is no longer default of type String, please change current usage to BarRendererConfig<String>. This is a breaking change.
  • BarTargetLineRendererConfig is no longer default of type String, please change current usage to BarTargetLineRendererConfig<String>. This is a breaking change.


  • Simplified API by removing the requirement for specifying the datum type when creating a chart. For example, previously to construct a bar chart the syntax was 'new BarChart<MyDatumType>()'. The syntax is now cleaned up to be 'new BarChart()'. Please refer to the online gallery for the correct syntax.
  • Added scatter plot charts
  • Added tap to hide for legends
  • Added support for rendering area skirts to line charts
  • Added support for configurable fill colors to bar charts


  • Update color palette. Please use MaterialPalette instead of QuantumPalette.
  • Dart2 fixes
