flutter 使用webView

第一步：安装webView

#webview
webview_flutter: ^3.0.2

第二步：写入页面

SizedBox(
    width: Get.width,
    height: Get.height,
    child: Padding(
           padding: EdgeInsets.only(top: 264.w),
           child: WebView(
           initialUrl: controller.url,
           onWebViewCreated: (WebViewController webViewController) {
               controller.webViewcController.complete(webViewController);
           },
           javascriptMode: JavascriptMode.unrestricted,
           backgroundColor: Colors.transparent,
           javascriptChannels: <JavascriptChannel>[
              _rechargeJavascriptChannel(),
            ].toSet(),
    )),
),

第三步：写入controller

class PublicWebViewController extends GetxController {
  String title = '';
  String url = '';
  final Completer<WebViewController> webViewcController = Completer<WebViewController>();

  @override
  void onClose() {
    // TODO: implement onClose
    super.onClose();
    if (webViewcController != null && webViewcController.future != null) {
      webViewcController.future.then((wController) {
        // wController.clearCache();
      });
    }
  }

  @override
  void onInit() {
    // TODO: implement onInit
    super.onInit();
    title = Get.arguments['title'];
    url = Get.arguments['url'];
  }
}
