Logging

Wingify by default logs all ERROR level messages to your device console. To gain more control over Wingify's logging behavior, you can use the logger parameter in the init configuration.

Logger Properties

Parameter	Type	Description
level	String	Level or Type of error. Could be one of the following: DEBUG, INFO, ERROR, TRACE, WARN
transports	List/Object	Custom logger implementation(s) for advanced log handling.

Examples

Example 1: Set log level to control the verbosity of logs

import 'package:wingify_fme_flutter_sdk/wingify.dart';
import 'package:wingify_fme_flutter_sdk/wingify/models/wingify_init_options.dart';

final wingifyInitOptions = WingifyInitOptions(
  sdkKey: 'YOUR_SDK_KEY',
  accountId: YOUR_ACCOUNT_ID,
  logger: {"level": "TRACE"} // DEBUG, INFO, ERROR, TRACE, WARN
);

// Initialize the SDK
final wingifyClient = await Wingify.init(wingifyInitOptions);

Example 2: Implement custom transport to handle logs your way

The transports parameter allows you to implement custom logging behavior by providing your own logging functions. You can define handlers for different log levels (TRACE, DEBUG, INFO, WARN, ERROR) to process log messages according to your needs.

import 'package:wingify_fme_flutter_sdk/wingify.dart';
import 'package:wingify_fme_flutter_sdk/wingify/models/wingify_init_options.dart';
import 'package:wingify_fme_flutter_sdk/logger/log_transport.dart';

// Create a custom logger implementation
class DartLogger implements LogTransport {
  @override
  void log(String level, String? message) {
    if (message == null) return;
    print("FE-Flutter: [$level] $message");
  }
}

// Initialize Wingify SDK with logger configuration
var transport = <String, dynamic>{};
transport["defaultTransport"] = DartLogger();

var logger = <Map<String, dynamic>>[];
logger.add(transport);

final wingifyInitOptions = WingifyInitOptions(
  sdkKey: 'YOUR_SDK_KEY',
  accountId: YOUR_ACCOUNT_ID,
  logger: {"level": "TRACE", "transports": logger},
);

// Initialize the SDK
final wingifyClient = await Wingify.init(wingifyInitOptions);

The custom logger implementation allows you to:

Process log messages according to your application's needs
Forward logs to your preferred logging service
Filter or transform log messages before they are displayed
Integrate with your existing logging infrastructure
