Flutter is the perfect tool to get started in IT or transition to it in 2023. And I'm the coach you've been looking for.
In this lesson, we'll get acquainted with Hive local storage in the Flutter infrastructure. Hive is a NoSql database. It's written in pure Dart, without any native code. This magical annihilator gun is incredibly fast and solves most of the problems programmers face when setting up local data storage. It's also ideal for caching.
By the way, caching is exactly what we'll be doing. Anyway, watch the video, because I'm so inspired there that I even cover some programming patterns.
During the course, we'll explore Flutter and how to build your first app. We'll learn how to program in Dart, learn about Flutter's basic widgets, how to work with the HTTP/DIO network, and learn about Flutter's core state management system, BLoC.
