Quiver log is a set of logging utilities that make it easy to configure and manage Dart's built in logging capabilities.Dart's built-in logging utilities are fairly low level. This means each time you start a new project you have to copy/paste a bunch of logging configuration code to setup output locations and logging formats. Quiver-log provides a set of higher-level abstractions to make it easier to get logging setup correctly. Specifically, there are two new concepts: appender and formatter. Appenders define output locations like the console, http or even in-memory data structures that can store logs. Formatters, as the name implies, allow for custom logging formats.
