loadData method

Future<void> loadData({ required String data, String mimeType = "text/html", String encoding = "utf8", WebUri? baseUrl, @Deprecated('Use historyUrl instead') Uri? androidHistoryUrl, WebUri? historyUrl, @Deprecated('Use allowingReadAccessTo instead') Uri? iosAllowingReadAccessTo, WebUri? allowingReadAccessTo, })

Loads the given data into this WebView, using baseUrl as the base URL for the content.

• mimeType argument specifies the format of the data. The default value is "text/html".
• encoding argument specifies the encoding of the data. The default value is "utf8". NOTE: not used on Web.
• historyUrl is an Android-specific argument that represents the URL to use as the history entry. The default value is about:blank. If non-null, this must be a valid URL. NOTE: not used on Web.
• allowingReadAccessTo, used in combination with baseUrl (using the file:// scheme), it represents the URL from which to read the web content. This baseUrl must be a file-based URL (using the file:// scheme). Specify the same value as the baseUrl parameter to prevent WebView from reading any other content. Specify a directory to give WebView permission to read additional files in the specified directory. NOTE: available only on iOS and MacOS.

NOTE for Windows: only the data parameter is used.

Officially Supported Platforms/Implementations:

• Android native WebView (Official API - WebView.loadDataWithBaseURL)
• iOS (Official API - WKWebView.loadHTMLString or Official API - WKWebView.load)
• MacOS (Official API - WKWebView.loadHTMLString or Official API - WKWebView.load)
• Web
• Windows (Official API - ICoreWebView2.NavigateToString)

        String encoding = "utf8",
        WebUri? baseUrl,
        @Deprecated('Use historyUrl instead') Uri? androidHistoryUrl,
        WebUri? historyUrl,
        @Deprecated('Use allowingReadAccessTo instead')
        Uri? iosAllowingReadAccessTo,
        WebUri? allowingReadAccessTo}) =>
    platform.loadData(
        data: data,
        mimeType: mimeType,
        encoding: encoding,
        baseUrl: baseUrl,
        androidHistoryUrl: androidHistoryUrl,
        historyUrl: historyUrl,
        iosAllowingReadAccessTo: iosAllowingReadAccessTo,
        allowingReadAccessTo: allowingReadAccessTo);
