Design And Research Of The Mobile Terminal Application Of Changxiang Health Based On Flutter Cross-platform

Under the traditional medical model,it is difficult for people to use fragmented time to understand and diagnose their own health problems.And people do not pay enough attention to mental health,rarely take the initiative to ask for mental health problems,unless health collection.Therefore,it is urgent to establish a health management mode under the Internet environment through technical means and methods such as mobile Internet,Internet+and intelligent terminals,so that people can understand and inquire about health problems in their leisure time.Based on this background,the Flutter cross-platform mobile terminal application of Changxiang Health is designed and implemented.The Flutter-based Changxiang Health mobile terminal application is a smart health application that integrates information collection,data analysis,online consultation,health consultation,and psychological counseling.The application provides multi-dimensional health management and system services from all aspects of healthy lifestyle,disease control and prevention,consultation and diagnosis of health problems.It aims to establish a faster,more accurate,more scientific and more comprehensive health management system,and to provide strong technical support and effective solutions to promote the development of health undertakings and maximize the improvement of people’s health.As the most popular cross-platform solution,Flutter uses self-rendering to quickly build Android and iOS apps,greatly improving development efficiency while maintaining performance.With Flutter as the basic framework,the design pattern of layered architecture is adopted to make each level independent of each other and decouple to the greatest extent.Each business is designed and developed in a modular way depending on the basic functions and components.It is also based on Bloc State Management,which solves the problem of confusing state management and cross-component communication as functionality increases.Login authentication adopts the mobile phone account plus verification code explicit authentication and token implicit authentication,which can not only reduce the direct reliance on user information but also ensure the security of user information to the greatest extent.In order to ensure the user experience,the system has done a lot of tests on network conditions,stability,compatibility,screen adaptation,and user security logins before going online,and optimized the places that do not meet the requirements to reduce system abnormalities and crash rates.Through continuous optimization and detection of problems,the system currently has a beautiful interface design,fast response speed,good user experience and good display effects for different models of mobile phones,which meet the expected design goals.
