Flutter Charting library

pub package

Material Design data visualization library written natively in Dart.

Supported charts

See the online gallery.

Using the library

The /example/ folder inside charts_flutter in the GitHub repo contains a full Flutter app with many demo examples.

0.4.0

  • Fixed export file to export ChartsBehavior in the Flutter library instead of the one that resides in charts_common. The charts_common behavior should not be used except internally in the charts_flutter library. This is a breaking change if you are using charts_common behavior.
  • 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.

0.3.0

  • 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

0.2.0

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

0.1.0

Initial release.
