+You can add error widget which will replace red screen of death. To add this into your app, see code below:
+```dart
+  @override
+  Widget build(BuildContext context) {
+    return MaterialApp(
+      navigatorKey: Catcher.navigatorKey,
+      //********************************************
+      builder: (BuildContext context, Widget widget) {
+        Catcher.addDefaultErrorWidget(
+            showStacktrace: true,
+            customTitle: "Custom error title",
+            customDescription: "Custom error description");
+        return widget;
+      },
+      //********************************************
+      home: Scaffold(
+          appBar: AppBar(
+            title: const Text('Plugin example app'),
+          ),
+          body: ChildWidget()),
+    );
+  }
+```
+You can provide optional parameters:
+* showStacktrace - show/hide stacktrace
+* customTitle - custom title for error widget
