Dio add custom log level

[mylukin]

Background

Currently, TalkerDioLogger does not support customizing log levels for different log types (requests, responses, errors). This limits flexibility in distinguishing critical logs (e.g., errors) from less important ones.

Code

  _dio.interceptors.add(
      TalkerDioLogger(
        talker: talker,
        settings: const TalkerDioLoggerSettings(
          enabled: true,
          logLevel: LogLevel.info, // custom log level
          printRequestHeaders: true,
          printResponseHeaders: false,
          printResponseMessage: true,
        ),
      ),
    );

Changes

1. Custom Log Levels:

   • Added logLevel to DioRequestLog and DioResponseLog, configurable via TalkerDioLoggerSettings.
   • Set DioErrorLog to always use LogLevel.error for better error visibility.

2. Enhanced TalkerDioLoggerSettings:

   • Introduced a logLevel option, defaulting to LogLevel.debug, allowing global customization for request and response logs.

Reasons for Changes

• Flexibility: Users can adjust log levels based on the environment (e.g., debug for development, info for production).
• Improved Error Handling: Highlighting error logs ensures critical issues are easily noticeable.
• Better Log Management: Aligns with user strategies for controlling log verbosity.

Impact

• Fully backward-compatible.
• Enhances configurability without affecting existing usage.

This update improves TalkerDioLogger's usability and adaptability for various logging needs.
