Flutter金融借贷服务插件finbox_lending_plugin的使用

该插件可以用于集成FinBox借贷SDK。

注意事项

以下信息将在集成时由FinBox团队提供：

• ACCESS_KEY
• SECRET_KEY
• LENDING_SDK_VERSION
• DC_SDK_VERSION
• COMMON_SDK_VERSION
• COMMON_FLAVOR
• LOGGER_SDK_VERSION
• CLIENT_API_KEY

添加插件

在local.properties文件中指定以下内容：

ACCESS_KEY=<ACCESS_KEY>
SECRET_KEY=<SECRET_KEY>
LENDING_SDK_VERSION=<LENDING_SDK_VERSION>
DC_SDK_VERSION=<DC_SDK_VERSION>
COMMON_SDK_VERSION=<COMMON_SDK_VERSION>
COMMON_FLAVOR=<COMMON_FLAVOR>
LOGGER_SDK_VERSION=<LOGGER_SDK_VERSION>

在pubspec.yaml文件中添加插件依赖：

dependencies:
  finbox_lending_plugin: any

初始化SDK

调用initSdk方法并传递所需参数：

FinBoxLendingPlugin.initSdk(
  "环境类型", // Environment
  "API密钥", // Api key
  "客户ID", // Customer ID
  "客户令牌", // Customer token
  "信用额度提款金额"); // Credit Line withdrawl amount

打开借贷屏幕

调用startLending方法开始借贷流程：

FinBoxLendingPlugin.startLending();

处理SDK旅程结果

在主页面的build方法内设置方法处理器：

FinBoxLendingPlugin.platform.setMethodCallHandler(_getJourneyResult);

创建一个方法来处理回调：

static Future<void> _getJourneyResult(MethodCall call) async {
  if (call.method == 'getJourneyResult') {
    var json = call.arguments;
  }
}

接收到的JSON格式如下：

{
  "code": "code",
  "screen": "screen",
  "message": "message"
}

错误代码

以下是错误代码及其描述：
