Flutter Basics

Currently (2022.7) the most popular cross-platform front-end framework, the official website slogan Build apps for any screen, which means that it can run on any front-end like a web page, and it needs to unify the front-end. I don't know if it can be achieved.Or be replaced later!

Bringing innovation to application development,Build and test applications for all front-ends (including - mobile, web, desktop, embedded) using one codebase.

Flutter is supported steadily by Google.

If the Android environment and other basic development environments have been built, the speed is still relatively fast.

Summary of emotion: 7 years have passed since 15 years of learning Android, and many things have changed dramatically.
The original relatively new things, smart phones, operating systems (Android IOS), language paradigms, compilers (Android Studio), small programs, etc. have now become very basic tools.
Some basic patterns have also matured and have been explored almost (the client code is divided into native and web (no matter what different name it takes, applet, quick application)).
So a more convenient and advanced upper-level tool is built on top of this.
