# Requirements and Installation

This guide provides the installation and configuration steps for Tonder's Flutter Full SDK.

## Prerequisites

You need to add the Skyflow Maven repository to your Android project configuration to handle secure data vaulting.

1. Add the Skyflow Maven repository to your Android project configuration. This repository contains the secure data vaulting components required for PCI DSS compliance:

```gradle title="android/build.gradle" theme={null}
maven {
    url '[https://maven.pkg.github.com/skyflowapi/skyflow-android-sdk](https://maven.pkg.github.com/skyflowapi/skyflow-android-sdk)'
    credentials {
        username = 'username'
        password = 'password'
    }
}
```

2. Enable AndroidX support in your project. This ensures compatibility with modern Android libraries and the Tonder SDK:

```ini title="android/gradle.properties" theme={null}
android.useAndroidX=true
```

## Installation

To install the Tonder Flutter Full SDK, you need to add the Full SDK package to your project and configure mobile environment permissions. The Full SDK provides a pre-built, inline checkout experience.

### Step 1: Install the SDK Package

Add the Full SDK package to your `pubspec.yaml` file or use `flutter pub add`:

```bash theme={null}
flutter pub add full_sdk
```

### Step 2: Configure Mobile Environment Permissions

You must grant internet permissions for the SDK to function correctly on native devices.

<Tabs>
  <Tab title="Android">
    Add the INTERNET permission to your `AndroidManifest.xml` file.

    ```xml theme={null}
    <uses-permission android:name="android.permission.INTERNET" />
    ```
  </Tab>

  <Tab title="iOS / macOS">
    For iOS and macOS, add the network client entitlement to your `.entitlements` files.

    ```xml theme={null}
    <key>com.apple.security.network.client</key>
    <true/>
    ```
  </Tab>
</Tabs>
