gauges library
Syncfusion flutter gauges library includes data visualization widgets such as radial gauge, which is used to create modern, interactive, and animated gauges that are used to craft high-quality mobile app user interfaces using Flutter.
To use, import package:syncfusion_flutter_gauges/gauges.dart.
