request method

Future<Map<String, dynamic>> request(String url, Map<String, dynamic> params, { required NetworkMethodType method, bool absoluteUrl = false, bool isRawResponse = false, bool isSimpleResponse = false, bool isNeedAutoSetupDeviceInfo = true, bool isUseMemoryCache = false, String? cacheKey, Map<String, String>? customHeaders, List<String>? ignoreErrorCodes, })

Http request.

• url .
• params The MapObj of HTTP Body.
• method NetworkMethodType.
• isRawResponse Returning the response raw data directly.
• isSimpleResponse The 'data' could be null or SimpleType at the response value.
• isNeedAutoSetupDeviceInfo Automatic invoking the _setupDeviceInfoIfNeeded.
• ignoreErrorCodes The response codes that will not be recognize.
