Initialization

SDK Initialization for Wepin Flutter Widget SDK

After installing the Wepin Flutter Widget SDK, the next step is to initialize the SDK. SDK initialization involves creating an instance of WepinWidgetSDK and using the init() function to proceed.

Import SDK

To use the Wepin Flutter Widget SDK, you first need to import the SDK. Add the following import statements:

import 'package:wepin_flutter_widget_sdk/wepin_flutter_widget_sdk.dart';
import 'package:wepin_flutter_widget_sdk/wepin_flutter_widget_sdk_type.dart';

Creating the WepinWidgetSDK Instance

Before creating an instance of WepinWidgetSDK, you must register your app's Android/iOS information in the Wepin Workspace.

App Registration

Using the registered app information, create an instance of WepinWidgetSDK. In the state init stage of the main.dart file, create and initialize the WepinWidgetSDK instance as follows:

main.dart

WepinWidgetSDK wepinSDK = WepinWidgetSDK(
    wepinAppKey: wepinAppKey, 
    wepinAppId: wepinAppId
);

SDK Initialization (init)

When initializing the Wepin Flutter Widget SDK, you can define the required widget properties.

await wepinSDK.init({WidgetAttributes? attributes});

Parameters

• attributes <WidgetAttributes>optional - Widget properties to define during initialization.

  • defaultLanguage <String>: Set the default language of the widget. The default value is ko, and currently supported languages are en, ja and ko.

  • defaultCurrency <String> Set the default currency of the widget. The default value is KRW, and currently supported currencies are USD, JPYand KRW.

Return Value

• Future<void>

Example

await wepinSDK.init(WidgetAttributes(
    defaultLanguage: 'ko',
    defaultCurrency: 'KRW',
));

Checking Initialization Status (isInitialized)

You can check whether the WepinSDK has been successfully initialized.

bool isInitialized = wepinSDK.isInitialized();

Parameters

• None

Return Value

• <bool> Returns true if the initialization was successful, and false if it failed.

Example

await wepinSDK.init(WidgetAttributes(
    defaultLanguage: 'ko',
    defaultCurrency: 'KRW',
));

if (wepinSDK.isInitialized()) {
  print('WepinSDK is initialized!');
}

Changing Language and Currency (changeLanguage)

You can change the language and currency of the widget.

wepinSDK.changeLanguage({String language, String currency});

Parameters

• language <String> Specifies the language to be displayed in the widget. Currently supported languages are en, ja and ko.

• currency <String> Specifies the currency to be displayed in the widget. Currently supported currencies are USD, JPY and KRW.

Example

wepinSDK.changeLanguage(
  language: 'ko',
  currency: 'KRW'
);
