GitHub Star Comparison
| No | Name | GitHub Stars | Description | Trend | License | Type | Official Site |
|---|---|---|---|---|---|---|---|
| 1 | logger | - | Small, easy-to-use, and extensible Dart/Flutter logging package inspired by Android logger that prints beautiful logs. Supports trace, debug, info, warning, error, and fatal levels. Shows logs at or above configured level in debug mode, omits all logs in release mode. | Established position as most popular Flutter logging solution in 2025. High support in Flutter developer community due to beautiful log formatting and conciseness available out of the box. Ensured Dart 3 compatibility and maintenance continuity through latest update in November 2024. | MIT | Beautiful Logger | Official |
| 2 | logging | - | More fundamental Dart logging package similar to Closure JS Logger and Java java.util.logging.Logger. Provides APIs for debugging and error logging. Enables individual configuration and monitoring, particularly useful in library development. Published 8 months ago with Dart 3 compatibility. | Continues as standard choice for Dart library development in 2025. Preferred by library creators due to design enabling applications to control logging from external libraries. Adopted in scenarios requiring basic but reliable logging functionality. | BSD-3-Clause | Library Logger | Official |
| 3 | dart:developer log | - | Standard logging functionality built into Dart and Flutter. Designed to work closely with package:logging, provides integration with Flutter DevTools. Meets basic logging requirements without external dependencies, enables direct display in development tools. | Widely used as basic debugging means in Flutter development in 2025. Debug experience improved through DevTools integration, adoption continues in learning stages and lightweight logging requirements. Valued in projects wanting to minimize dependencies due to standard inclusion. | BSD-3-Clause | Standard Function | Official |
| 4 | FLog | - | Advanced logging framework providing quick and simple logging solution. Saves all logs to database and enables export as zip file. Provides functionality specialized for log collection and analysis in production apps. | Adoption increasing in scenarios requiring log management in production Flutter/Dart apps in 2025. Demonstrates power in problem analysis and support handling after app distribution through database storage and export functionality. Selection examples expanding in enterprise-level app development. | MIT | Database Logger | Official |
| 5 | Talker | - | Handy toolkit for mobile app debugging. Inspired by web inspectors and customized for mobile application development. Modern solution providing comprehensive debugging environment through simple yet versatile functionality. | Emerging package gaining attention from developers seeking improved debugging experience in Flutter development in 2025. Solves traditional mobile development debugging constraints through web inspector-like functionality. Adoption seen in teams prioritizing development efficiency improvement. | MIT | Debugging Suite | Official |
| 6 | print() (Built-in) | - | Dart's standard output function. Suitable for rapid log output in learning stages and simple scripts as simplest debugging means. Immediately available without configuration, but has feature limitations in full-scale application development. | Usage continues in early stages of Dart/Flutter learning and quick debugging in 2025. However, migration to logger or logging packages recommended for full-scale Flutter app development. Print statement removal becomes important task in development to release process. | BSD-3-Clause | Native Function | Official |
