Mobile WebView

GoCharting does not ship separate iOS / Android chart SDKs. Native apps load the JavaScript SDK inside a WebView and talk to it over a bridge.

Supported hosts:

• React Native (react-native-webview)
• Flutter (WebView / JavascriptChannel)
• Android (WebView + JavascriptInterface)
• iOS (WKWebView + message handlers)

Pattern

1. Host a page that calls createChart(..., { isNativeApp: true }).
2. Keep window.chart (or similar) for native → JS commands.
3. Listen for sendToNative / appCallback messages for JS → native events.
4. Drive symbol, interval, orders, and sheets from native chrome.

window.chart = createChart("#chart", {
	symbol: "BYBIT:FUTURE:BTCUSDT",
	interval: "1m",
	datafeed: myDatafeed,
	licenseKey: "YOUR_LICENSE_KEY",
	isNativeApp: true, // mobile canvas; host owns toolbars
	appCallback: (event) => {
		// Also posted to the native bridge when isNativeApp is true
	},
});

For production native shells, prefer isNativeApp: true.
