摘　　要：移动端应用程序需要存储与访问的数据越来越多,而移动端设备的存储空间有限,很难满足用户需要,在进行移动端应用程序开发时,选择合适、高效的数据存储与访问机制受到普遍关注。针对Google推出的Flutter跨平台移动开发框架提供的key-value键值对、File文件、SQLite数据库和网络4种数据存储访问机制,深入阐述了它们的内在工作原理,给出了具体实现方法和实现代码。最后,根据4种数据存储访问机制各自的特点和实际的应用程序开发需求,分析了每种机制的应用场景。Mobile applications need to store and access more and more data,and the storage space of mobile devices is limited,it is difficult to meet the needs of users.When developing mobile applications,the selection of appropriate and efficient data storage and access mechanism is widely concerned.In view of the four data storage and access mechanisms provided by Google′s Flutter cross-platform mobile development framework,such as key-value pair,File files,SQLite database and network,this paper explains their inner working principles in depth,and gives the specific implementation methods and implementation codes.Finally,according to the characteristics of the four data storage access mechanisms and the actual application development requirements,the application scenarios of each mechanism are analyzed.
