+title: PnP Flutter SDK - v5 to v6
+description: "PnP Flutter SDK - v5 to v6 | Documentation - Web3Auth"
+sidebar_label: v5 to v6
+---
+
+This migration guide provides steps for upgrading from version v5 to v6 of the PnP Flutter SDK. The
+guide outlines significant changes and enhancements, including the support of Web3Auth OpenLogin
+version v9, and Wallet Services v3.
+
+## Breaking Changes
+
+### `getSignResponse` is now removed.
+
+In v6, we try to improve the developer experience by removing the `getSignResponse` method and
+returning the result in the `request` method itself.
+
+Previously, after calling the `request` method, developers had to use the `getSignResponse` method
+to retrieve the `SignResponse`. In the latest version v6, the `request` method will return the
+`SignResponse` directly.
+
+```dart
+try {
+  List<dynamic> params = [];
+  // Message to be signed
+  params.add("Hello, Web3Auth from Flutter!");
+  // User's EOA address
+  params.add("<User Address in Hex>");
+
+  // add-next-line
+  final response = await Web3AuthFlutter.request(
+    ChainConfig(
+      chainId: "0x1",
+      rpcTarget: "https://mainnet.infura.io/v3/$key",
+    ),
+    "personal_sign",
+    params,
+  );
+
+  // remove-next-line
+  final response = await Web3AuthFlutter.getSignResponse();
+
+  log(response.toString());
+} on UserCancelledException {
+  log("User cancelled.");
+} catch(e) {
+  log("Unknown exception occurred");
+}
+```
+
+## Minimum Android SDK Version
+
+The minimum Android SDK version for the PnP Flutter SDK is now 26. Please update your app level
+gradle file to set the minimum SDK version to 26.
+
+```gradle
+defaultConfig {
+    // ...
+    // add-next-line
+    minSdkVersion 26 //flutter.minSdkVersion
+    // remove-next-line
+    minSdkVersion 24 //flutter.minSdkVersion
+    // ...
+}
+```
+
+## Enhancements
+
+In the latest version v6, we have added support for the Web3Auth Auth Service version v9, and Wallet
+Services v3. In Wallet Services v3, the prebuilt wallet UI now supports the swap functionality
+allowing users to swap to their favorite token from the app itself.
