Installation

Add this to your pubspec.yaml:

dependencies:
  stock_chart_flutter: ^0.1.2

Usage

import 'package:stock_chart_flutter/stock_chart_flutter.dart';

final candles = <CandleData>[
  CandleData(
    time: DateTime(2026, 1, 1),
    open: 10,
    high: 12,
    low: 9,
    close: 11,
    volume: 12000,
  ),
];

StockCandlestickChart(
  data: candles,
  maPeriods: const [5, 10, 20],
  onSelected: (item) {
    // handle selected candle
  },
)

Tencent quote-style screen:

// Starts empty. Pass a symbol only when you want to fetch remote quotes.
const TencentStockChartPage()

TencentStockChartPage(
  symbol: 'sz001896',
  autoRefreshSeconds: 3,
)

The example app starts empty and includes a symbol input. Enter a Tencent-style code such as sz001896 or sh600519; six-digit A-share codes are normalized automatically (600519 becomes sh600519, other six-digit codes become sz...). You can also pass the initial symbol in the URL, for example http://localhost:62436/?symbol=sz001896.

Line chart:

final points = <LinePoint>[
  LinePoint(time: DateTime(2026, 1, 1, 9, 30), value: 10.2),
  LinePoint(time: DateTime(2026, 1, 1, 9, 31), value: 10.4),
];

StockLineChart(
  data: points,
  onSelected: (item) {
    // handle selected point
  },
)
