Is flutter being quietly abandoned? On the future of flutter

In today's rapid iterative development environment ,** Can achieve “ A set of code 、 Multi terminal operation ”** It is the dream of many Internet development teams , Ali 、 Tencent has also made many attempts , So is meituan ！ Focus on the development team of meituan , They have tried many cross platform development frameworks ：React Native、PWA、Weex wait . But they have not been well solved , Until I met Flutter.

Flutter What are the advantages ：

1. Open source

It is because Flutter Open source attribute of , So with the crazy support of global developers , In recent years flutter Rapid development , More and more perfect , Now Flutter3.0 Even more brilliant , I hope that in the near future, we can really achieve a set of code multi terminal deployment .

2. Stable

Flutter UI Due to self drawing UI, Thus avoiding the platform level UI And various compatibility problems caused by system upgrade . However, as a cross platform development technology, it is inevitable to maintain the underlying adaptation layer and various plug-ins to realize the communication with the original platform , This is a common problem of all cross platforms .

3. Efficient

For developers , Use Flutter Development and application are very efficient .Flutter Well received Hot Reload Functions can be found in 1 Seconds to UI Update , The development operation cycle is greatly shortened .

Flutter It provides a complete set of solutions from the low level rendering logic to the upper level development language , With cross platform 、 high fidelity 、 High performance and other excellent features . So from the release , The heat is rising all the way , It is eagerly favored by developers , There are also Today's headline 、 Ali idle fish 、 tencent Now And so on .

However, many of my friends told me that he was learning or intended to learn Flutter , But most of them have encountered these troublesome problems ：

• I've seen a lot Flutter Teaching video of , But the feeling flutter Pay too much attention to the application layer API Introduction of various parameters and implementation details , It's a little hard to learn .
• Flutter Everything from language to development framework is new , The accumulation of the technology stack must start from scratch , It's hard to learn .

In fact, if you want to learn well Flutter, We should not just stay at the level of detail , More important Go deep into its principle 、 Design ideas and general concepts .

meanwhile , Now there's something on the market about Flutter There are few systematic learning materials , But I have collected and sorted out a copy before 15 Project development of Dachang in Carefully sorted out **《Flutter Basic to core principles practical manual 》**, Can help you Quick start Flutter Development and application , Master the essence and establish your own knowledge system . There are friends who need the full version , can Click here or leave a message Flutter Can receive

summary

No matter what era of development technology , The problem to be solved is nothing more than ： performance , Development efficiency and hot update . And the first two Flutter It's almost solved perfectly , As for the hot update, I believe that with the continuous update iteration , There will be more and more excellent solutions .

I Believe flutter This cross platform development technology is the future ,flutter It's hard to say whether you can be king in the future , There may be a better development framework later , So now hurry to learn flutter, Not only is it now profitable , In the near future, new technologies will be produced , You can get started faster , Get a big bonus ！
