Overview
jmespath is a Dart implementation of the JMESPath query language, designed to extract and transform data from JSON structures. It allows developers to write expressive queries to navigate nested JSON objects, filter arrays, and perform operations like sorting and mapping. Ideal for parsing API responses or configuration files, it simplifies working with complex JSON data without writing verbose code. The package supports all major platforms including Android, iOS, Web, macOS, Windows, and Linux.
