+title: Generic types in PopScope
+description: >
+  Added a generic type in PopScope class and updated the onPopInvoked
+  function signature.
+---
+
+## Summary
+
+Added a generic type in [`PopScope`][] class and replaced the [`onPopInvoked`][]
+with a new method [`onPopInvokedWithResult`][]. The new method takes a boolean
+`didPop` and a `result` as position parameters.
+
+Also replaced the [`Form.onPopInvoked`] with [`Form.onPopInvokedWithResult`][]
+for the same reason.
+
+## Context
+
+Previously, `PopScope` didn't have a way to access the pop result when `onPopInvoked`
+was called. The generic type is added to the `PopScope` class
+so that the new method `onPopInvokedWithResult` can access the type-safe result.
+
+## Description of change
+
+Added a generic type in `PopScope` class and a new method `onPopInvokedWithResult`. 
+The `onPopInvoked` was deprecated in the favor of `onPopInvokedWithResult`.
+
+Also added a new method `onPopInvokedWithResult` to `Form` to replace `onPopInvoked`.
+
+## Migration guide
+
+Code before migration
+
+```dart
+import 'package:flutter/material.dart';
+
+void main() {
+  runApp(
+    MaterialApp(
+      navigatorKey: nav,
+      home: Column(
+        children: [
+          Form(
+            canPop: false,
+            onPopInvoked: (bool didPop) {
+              if (didPop) {
+                return;
+              }
+              launchConfirmationDialog();
+            },
+            child: MyWidget(),
+          ),
+          PopScope(
+            canPop: false,
+            onPopInvoked: (bool didPop) {
+              if (didPop) {
+                return;
+              }
+              launchConfirmationDialog();
+            },
+            child: MyWidget(),
+          ),
+        ],
+      ),
+    ),
+  );
+}
+```
+
+Code after migration
+```dart
+import 'package:flutter/material.dart';
+
+void main() {
+  runApp(
+    MaterialApp(
+      navigatorKey: nav,
+      home: Column(
+        children: [
+          Form(
+            canPop: false,
+            onPopInvokedWithResult: (bool didPop, Object? result) {
+              if (didPop) {
+                return;
+              }
+              launchConfirmationDialog();
+            },
+            child: MyWidget(),
+          ),
+          PopScope<Object?>(
+            canPop: false,
+            onPopInvokedWithResult: (bool didPop, Object? result) {
+              if (didPop) {
+                return;
+              }
+              launchConfirmationDialog();
+            },
+            child: MyWidget(),
+          ),
+        ],
+      ),
+    ),
+  );
+}
+```
+
+The generic type should match the generic type of the [`Route`]
+that the `PopScope` is in.
+If the route uses `int` as its generic type, consider using `PopScope<int>`.
+
+If the `PopScope` widgets are shared across multiple routes with
+different types, you can use `PopScope<Object?>` to catch all possible types.
