通過SharedPreferences可以實(shí)現(xiàn)Flutter和native的數(shù)據(jù)共享，從而避免了頻繁的通信。

1.Flutter保存數(shù)據(jù)

SharedPreferences _prefs =await SharedPreferences.getInstance();

_prefs.setString("guid", contactInfo.name);

2.native（Android）獲取數(shù)據(jù)

SharedPreferences share=context.getSharedPreferences("FlutterSharedPreferences",Activity.MODE_PRIVATE);

String guid=share.getString("flutter.guid","");

從native的調(diào)用方式可以看出，F(xiàn)lutter將數(shù)據(jù)存儲(chǔ)在FlutterSharedPreferences，并在每個(gè)key前加上了flutter.
