Lao Meng Guide: it took one year to sort out and complete the detailed usage of 330 + components, including not only UI components, but also functional components.
Although you have sorted out the basic usage of 330 + components, you are not allowed to learn each one. Basically, you can solve 80% of the problems by mastering 20% of any technology. Therefore, you can start the project by learning the basic components. As for other controls, you only need to browse, When working on a project, if you encounter some functions, you can remember that flutter has provided this component.
Therefore, don’t be afraid to see 330 + components. This is not an article that makes you get started to give up, but an article that makes you get started faster. I hope you take this as a reference book and look it up when you need it.
What controls should I learn? Don’t worry, I will share my official account (end of the paper with two-dimensional code, or direct search for Flutter). This series of articles contains a large number of common cases and effects in real projects, which will help you enter the Flutter gate as soon as possible in Flutter.
330 + components have been sorted into PDF, with a total of658Page.
Let’s take a look at the overall inheritance diagram of components.
There are only 4 direct subclasses of widgets (in fact, there is an abstract class)
RenderObjectWidgetThere are 89 and its subclasses:
ProxyWidgetThere are 34 and its subclasses:
StatelessWidgetThere are 89 and its subclasses:
StatefulWidgetUp to 141 subclasses
I want to thank many like-minded friends, such asRock，I principal ，K423-D，Ordinary programmer，freely flowing style of writing。 They provide very quality articles.
