推荐答案

我认为，可以通过两种方式解决此问题.他们在下面.

In my opinion, this problem can be resolved in two ways. They are below.

我检查了一个项目，发现SharedPreferencesPlugin.h具有以下代码.

I checked in one of my project and found SharedPreferencesPlugin.h has following code.

// Copyright 2017 The Chromium Authors. All rights reserved.

#import <Flutter/Flutter.h>

@interface FLTSharedPreferencesPlugin : NSObject <FlutterPlugin>
@end

此文件位于位置: (mysiyaram是项目名称)

This file is present at location : (mysiyaram is the project name)

现在，您可能有两种方法可以解决此问题. 方案A:您使用上面的代码手动创建文件.它不包含任何特定于版本的信息.

Now you might have two ways to solve this issue. Plan A : You create the file manually with the code above. It doesn't contain any version specific info any way.

计划B:创建另一个虚拟项目，在其中添加共享的首选项.并将文件(或文件夹结构)从虚拟项目复制到您的项目.

Plan B : Create another dummy project, add shared preferences in there. And copy the file (or folder structure) from the dummy project to your project.

注意:由于我不知道结构解决方案，因此请采用此选项作为解决方法.
