# Localization

This asynchronous method allows you to change the language used by the Tyrads SDK. It updates the SDK's internal locale settings.

```dart
await Tyrads.instance.changeLanguage("en");
```

#### Parameters:

* `languageCode` (String): A string representing the desired language code (e.g., "en" for English, "es" for Spanish, "fr" for French). This should be a valid ISO 639-1 language code.

#### Usage Example:

```dart
import 'package:tyrads_sdk/tyrads_sdk.dart';

ElevatedButton(
  onPressed: () async {
    await Tyrads.instance.changeLanguage('es'); // Change to Spanish
  },
  child: Text('Change to Spanish'),
),
```

#### Notes:

* This method persists the selected language in shared preferences so that it persists between app sessions.
* Make sure your application and the Tyrads SDK support the language code you are passing, otherwise english will be set.
* This method is asynchronous because it involves writing to shared preferences.
* Consider providing a language selection UI in your application that allows users to choose their preferred language if not Sdk itself provides user to select prefered language.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://sdk-doc.tyrads.com/flutter/initialization/localization.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
