# PnP Flutter SDK - 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[​](#breaking-changes "Direct link to Breaking changes")

### `getSignResponse` is now removed.[​](#getsignresponse-is-now-removed "Direct link to 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.

```
try {
  List<dynamic> params = [];
  // Message to be signed
  params.add("Hello, Web3Auth from Flutter!");
  // User's EOA address
  params.add("<User Address in Hex>");

  final response = await Web3AuthFlutter.request(
    ChainConfig(
      chainId: "0x1",
      rpcTarget: "https://mainnet.infura.io/v3/$key",
    ),
    "personal_sign",
    params,
  );

  final response = await Web3AuthFlutter.getSignResponse();

  log(response.toString());
} on UserCancelledException {
  log("User cancelled.");
} catch(e) {
  log("Unknown exception occurred");
}

```

## Minimum Android SDK version[​](#minimum-android-sdk-version "Direct link to 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.

```
defaultConfig {
    // ...
    minSdkVersion 26 //flutter.minSdkVersion
    minSdkVersion 24 //flutter.minSdkVersion
    // ...
}

```

## Enhancements[​](#enhancements "Direct link to 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.
