Flutter

With AppKit Flutter, you can easily let people interact with multiple EVM compatible wallets and blockchains.

Let's get started with the installation and configuration!

Installation

1. • Add reown_appkit as dependency in your pubspec.yaml and run flutter pub get (check out the latest version)
   • Or simply run flutter pub add reown_appkit
2. • Locate your /ios/Podfile file and add the following as the first line:

platform :ios, '13.0'

3. • Run $ pod install inside /ios folder.
4. • You should now be able to run your app with flutter run --dart-define=PROJECT_ID={your_project_id}

Enable Installed Wallet Detection

To enable AppKit to detect installed wallets on the device, you need to make specific changes to the native sides of the project.

iOS

1. Open your Info.plist file.
2. Locate the <key>LSApplicationQueriesSchemes</key> section.
3. Add the desired wallet schemes as string entries within the <array>. These schemes represent the wallets you want to detect.
4. Refer to our Info.plist example file for a detailed illustration.

Example:

<key>LSApplicationQueriesSchemes</key>
<array>
  <string>metamask</string>
  <string>trust</string>
  <string>safe</string>
  <string>rainbow</string>
  <!-- Add other wallet schemes names here -->
</array>

Android

1. Open your AndroidManifest.xml file.
2. Add your <queries>...</queries> schemes outside of <application /> scope.
3. Refer to Android Specs for more information.

Example:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android">

    <queries>
        <package android:name="io.metamask"/>
        <package android:name="com.wallet.crypto.trustapp"/>
        <package android:name="io.gnosis.safe"/>
        <package android:name="me.rainbow"/>
        <!-- Add other wallet schemes names here -->
    </queries>

    <application>
        ...
    </application>
</manifest>

Enable Coinbase Wallet

Since Coinbase Wallet uses its own SDK, there are a few extra but simply steps to do if you are planning to include and support it.

iOS

1. Open your Info.plist file.
2. Locate the <key>LSApplicationQueriesSchemes</key> section.
3. Include <string>cbwallet</string> scheme as mentioned above in previous section

Example:

<key>LSApplicationQueriesSchemes</key>
<array>
  <string>cbwallet</string>
  <!-- Any other scheme previously added -->
</array>

4. Make sure pods are installed, otherwise run pod install inside your /ios folder.
5. Open your /ios/Runner.xcworkspace file with Xcode and add the following code in AppDelegate.swift file:

import CoinbaseWalletSDK

override func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
    if #available(iOS 13.0, *) {
      if (CoinbaseWalletSDK.isConfigured == true) {
        if (try? CoinbaseWalletSDK.shared.handleResponse(url)) == true {
            return true
        }
      }
    }

    return super.application(app, open: url, options: options)
}

override func application(_ application: UIApplication, continue userActivity: NSUserActivity, restorationHandler: @escaping ([UIUserActivityRestoring]?) -> Void) -> Bool {
    if #available(iOS 13.0, *) {
      if (CoinbaseWalletSDK.isConfigured == true) {
        if let url = userActivity.webpageURL,
            (try? CoinbaseWalletSDK.shared.handleResponse(url)) == true {
            return true
        }
      }
    }

    return super.application(application, continue: userActivity, restorationHandler: restorationHandler)
}

Checkout out the AppDelegate.swift file from our sample dapp for reference.

Android

1. Open your AndroidManifest.xml file.
2. Add <package android:name="org.toshi"/> scheme inside <queries>...</queries> as mentioned above in previous section

Example:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android">

    <queries>
        <package android:name="org.toshi"/>
        <!-- Any other scheme previously added -->
    </queries>

    <application>
        ...
    </application>
</manifest>

note

If you encounter issue related to coinbase_wallet_sdk in regards of AGP 8.x Compatibility, please override coinbase_wallet_sdk dependency in you pubspec.yaml file as follows:

environment:
  ...

dependencies:
  ...

dependency_overrides:
  coinbase_wallet_sdk:
    git:
      url: https://github.com/WalletConnect/wallet-mobile-sdk.git
      path: flutter
      ref: beba5b377e32554f5c00ee08c4df509d9078dbf1

dev_dependencies:
  ...
  

Disable Coinbase Wallet

Coinbase Wallet is enabled by default even if, in order to function properly, a few steps has to be done as described in the previous section. However, if you don't want to include/support Coinbase Wallet on your app you just need to pass Coinbase Wallet id fd20dc426fb37566d803205b19bbc1d4096b248ac04548e3cfb6b3a38bd033aa to excludedWalletIds options Array.
