Overview

The at_viz package is for Flutter developers who want to build beautiful and customizable charts and gauges.

This open source package is written in Dart, and it supports Flutter with the following widgets:

SimpleRadialGauge

ScaleRadialGauge

SimpleLinearGauge

AtTimeSeriesLineChart

AtTimeSeriesBarChart

We welcome suggestions you may have to create more charts/gauges or to add features to already created ones.
