## Configure the Platforms

The `flutter create` template does not include the configuration the plugin needs.

For Android, add the JitPack repository, which hosts the plugin's native dependency:

```kotlin title="android/build.gradle.kts" showLineNumbers
allprojects {
repositories {
google()
mavenCentral()
maven { url = uri("https://jitpack.io") }
}
}
```

Then replace the template's `minSdk = flutter.minSdkVersion` with 26, which the plugin requires:

```kotlin title="android/app/build.gradle.kts" showLineNumbers
android {
defaultConfig {
minSdk = 26
}
}
```

For iOS, build with CocoaPods rather than Swift Package Manager. This also generates `ios/Podfile`, which the next step edits:

```bash
flutter config --no-enable-swift-package-manager
flutter pub get
```

Then set the platform to 16 and add the native SDK as a Git pod:

```ruby title="ios/Podfile" showLineNumbers
platform :ios, '16.0'

# ...

target 'Runner' do
use_frameworks!

pod 'ThunderID', :git => 'https://github.com/thunder-id/ios-sdks', :branch => 'main'

flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__))
target 'RunnerTests' do
inherit! :search_paths
end
end
```

Document the Android TLS limitation.

adb reverse maps the port only. It does not make Android trust the local instance's self-signed HTTPS certificate. The PR objective confirms that local Android access still fails until the SDK exposes allowInsecureConnections.

State this limitation after the adb reverse command. Do not present these steps as sufficient for Android local sign-in. Document a trusted certificate as the required workaround, or state that users must wait for SDK support.

  • docs/content/getting-started/connect-your-application/flutter.mdx#L343-L350: Add the Android self-signed-certificate limitation.
  • docs/versioned_docs/version-v1.0.x/getting-started/connect-your-application/flutter.mdx#L343-L350: Add the same limitation.

local Android sign-in; require a trusted certificate or instruct users to wait
