Demo

Install

dependencies:
  flutter_speedometer_gauge: ^0.1.0

Usage

import 'package:flutter_speedometer_gauge/flutter_speedometer_gauge.dart';

SpeedometerGauge(
  min: 0,
  max: 240,
  value: 126,
  units: 'km/h',
  segments: const [
    GaugeSegment(to: 120, color: Colors.green),
    GaugeSegment(to: 180, color: Colors.orange),
    GaugeSegment(to: 240, color: Colors.red),
  ],
  // Optional:
  size: 260,
  startAngleDeg: 150,
  sweepAngleDeg: 240,
  majorTickCount: 7,
  minorTicksPerInterval: 4,
);

Tips

• For compact UIs, reduce size and majorTickCount.
• For a semicircle gauge, set startAngleDeg: 180 and sweepAngleDeg: 180.
• To hide ticks entirely, set showTicks: false.
