In this Flutter course we are going to learn to build a macOS app and a local data storage using Hive package which help us to create NoSQL database, it internally make use of key-value and work well both with Android, iOS, Desktop and Web.
We will build a native looking macOS app with flutter using the flutter library macos_ui and we will use a Hive for local storage. We will also lean about flutter DataGrid and create a DataTable

macos_ui

Flutter widgets and themes implementing the current macOS design language.

Flutter DataGrid (DataTable) library

The Flutter DataTable or DataGrid is used to display and manipulate data in a tabular view. It is built from the ground up to achieve the best possible performance, even when loading large amounts data.

Hive

Hive is a lightweight and blazing fast key-value database written in pure Dart. Inspired by Bitcask.

Features

• Cross platform: mobile, desktop, browser

• Great performance (see benchmark)

• Simple, powerful, & intuitive API

• Strong encryption built in

• NO native dependencies

• Batteries included

Hive is also one of the best options when it comes to cross-platform support. You don't have to include binaries, and it works in the browser using IndexedDB.

Hive is very performant because it has little overhead compared to relational databases. The API is very close to how the data is stored on the disk.

Key-value databases can be used to store almost any kind of data. For example:

• User profiles

• Session information

• Article/blog comments

• Messages

• Shopping cart contents

• Product categories

• Binary data

• etc.
