What is VSCode
Visual Studio Code (VS Code for short) is a free code editor developed by Microsoft that supports operating systems such as Windows, Linux and macOS. It supports testing and has built-in Git version control functions. It also has development environment functions, such as Code completion (similar to IntelliSense), code snippets, code refactoring, etc. The editor supports user-customized configuration, such as changing various attributes and parameters such as theme colors, keyboard shortcuts, etc. It also has built-in extension management functions in the editor. VSCode also supports Flutter development. In my daily development, I will use VSCode more than Android Studio.
