I am using react-native-webview
for rendering a webview. When I navigate from one page to other inside the webview and then try to go back using this.webviewref.goBack()
I get the exception of nodeHandle expected to be non-null
.
Here is my piece of code
<View style={{ flex: 1 }}>
<Header
headingText={headerText}
onpress={() => {
// this.dispatchCustomEvent(BACK_PRESS);
if (this.canGoBack) {
this.webViewRef.goBack();
} else NavigationActions.pop();
}}
/>
<WebView
source={{ uri: "http://localhost:3001/invite/" }}
bounces={false}
javaScriptEnabled={true}
ref={webViewRef => (this.webViewRef = webViewRef)}
// injectedJavaScript={patchPostMessageJsCode}
onMessage={event => {
const { type, data } = JSON.parse(event.nativeEvent.data);
console.log({ type });
console.log({ data });
this.handleEvent(type, data);
}}
onNavigationStateChange={navState =>
(this.canGoBack = navState.canGoBack)
}
/>
</View>
console logging this.webViewRef
shows that the goBack
method exists in the weViewRef
The code for which throws the nodeHandle expected to be non-null
can be found here https://github.com/react-native-community/react-native-webview/blob/master/src/WebView.ios.tsx
I am unable to understand what is the problem with getWebViewHandle
and why nodeHandle
is null.
I had the same problem. It turns out that my react-native version is too low. It requries at least 0.57. After upgraded to 0.59.5 and other dependencies, this problem disappears.
