Flutter Web的Shared_Preferences? [英] Shared_Preferences for Flutter Web?

问题描述

Shared_preferences( https://pub.dev/packages/shared_preferences )似乎不起作用用于Flutter for Web.

Shared_preferences (https://pub.dev/packages/shared_preferences) doesn't seem to work for Flutter for Web.

按下按钮时会调用以下功能.

I have the following function that's called when a button is pressed.

 getEmail() async {
    print("reached 1st line");
    SharedPreferences prefs = await SharedPreferences.getInstance();
    print("reached 2nd line");
    String _confirmedEmail = prefs.getString('_confirmedEmail') ?? "";
)

它显示到达第一行"，但不显示到达第二行"，这意味着程序不会经过await语句.有趣的是，我也没有任何错误.似乎只是忽略了await语句之后的其余功能.

It prints "reached 1st line" but not "reached 2nd line", which means the program doesn't go past the await statement. Interestingly I don't get any error either. It seems to just ignore the rest of the function after the await statement.

在Flutter for Web中存储共享首选项的最佳选择是什么?

好消息，版本0.5.6 shared_prefs 默认情况下flutter支持网络

Great news, from version 0.5.6 shared_prefs flutter supports web by default

现在它包括网络的共享首选项

您的代码应该可以正常工作，而无需更改，只需更新 pubspec.yaml
