基于谷歌Flutter框架媒体资讯App的设计与实现

Design and Implementation of Media Information AppBased on Google Flutter FrameworkAbstract:In today's society,with the development of economy and technology,people's pace of life is becoming faster and faster,people's reading time is becoming less andless,and fragmented reading is becoming more and more popular.For the same clientdevelopers of the Internet,version iterations are becoming more and more frequent.For thesame mobile app,at least two platforms should be released,because of these differentplatforms,Different systems lead to the fact that traditional native development efficiency canno longer meet the growing business requirements in multiple business scenarios,such asAndroi and IOS.Once the requirements are changed,both platforms need to be updated andre released.This will increase the development cost of both terminals of a company.The mainperformance is as follows:(1).dynamic content demand increases:when the demand changes,the traditional nativeapplication needs to carry out version iteration to update the content,but the application onthe shelf audit is periodic.(2).the business demand changes rapidly,and the development cost is high:because thenative development generally needs to maintain two development teams,Android and IOS,when the version is iterated,both the labor cost and the test cost will increase.In this case,the cost for developers to develop apps is rising,and the process of puttingthem on the shelf and version iteration is tedious.Many IT giants have launched many crossplatform frameworks,such as Facebook's react native,Alibaba's weex,however,is far lesspopular than the native development due to its performance defects and difficult to achievecomplex operation.However,the cross platform framework of flutter launched by Google in2015 has experienced more than five years of development.Many problems of flutter itselfare also being repaired,and now it is quite mature,so it is used as a cross platform The firstchoice framework of technology is to develop this kind of cross platform informationapplication.When researching and leaming flutter,it also makes a little contribution to thesoftware ecology of flutter and provides an information application that is not limited by the
