Study of data storage access mechanism based on Flutter development framework

Abstract： 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.
