前言

本库是跨平台库，可以运行在android,linux,window等平台。

理论上也支持mac，ios等平台，也写了相关代码，但我没有mac，ios等设备，因此就将相关依赖注释起来了，没有为其构建并测试打包。 如果你希望支持mac，ios等平台，可以将相关gradle中的注释放开进行构建和测试。

若是仅在android平台使用

由于本库是跨平台库，因此，相关依赖会与android版本有所差别，并内置了datastore读写实现。 因此若是仅为android平台构建应用，也可以使用

android版本 专为android平台维护，支持datastore,sharedpreference,mmkv等。

若希望构建一个跨平台应用

版本

implementation("com.github.Knightwood.ComposePreferenceMultiplatform:preference-ui-compose-multi-android:1.0.0")
implementation("com.github.Knightwood.ComposePreferenceMultiplatform:preference-ui-compose-multi-desktop:1.0.0")
implementation("com.github.Knightwood.ComposePreferenceMultiplatform:preference-ui-compose-multi:1.0.0")

• 一些破坏性改动
• 方法名 getReadWriteTool 改为 getSingleDataEditor
• 接口名 IPreferenceReadWrite 改为 IPreferenceEditor

运行示例应用：

运行desktop

首先点击run/debug configurations

步骤：

1. 点击添加，选择gradle，在run的输入框中写入desktopRun -DmainClass=MainKt --quiet

2. gradle project 选择 ComposePreference-Multi:composeApp

运行android app

直接在run/debug configurations下拉框中选择composeApp,点击run

使用：

本库与android版使用同一个读写接口，因此，在使用跨平台android依赖时，也可以依赖android版中的mmkv和sharedpreference读写工具。

1. 手动生成DataStore文件，获取DataStorePreferenceHolder

//android
val dataStore = getDataStore(applicationContext,"ee.preferences_pb")
//desktop
val dataStore = getDataStore("/home/kiylxf/桌面/新建文件夹/ee.preferences_pb")
//获取holder
val holder = DataStorePreferenceHolder.instance(dataStore)

2. 构建preference页面 构建preference页面等功能与android版 相同

PreferencesScope(holder = holder) {
        val customNodeName = "customNode"
        //创建一个自定义节点
        val node = holder.registerDependence(customNodeName, true)
        PreferencesCautionCard(title = "PreferencesCautionCard")
        PreferencesHintCard(title = "PreferencesHintCard")

            icon = Icons.Filled.Favorite,
            endIcon = Icons.Filled.Share
        )
        PreferenceItem(
            title = "绝大多数可带图标",
            icon = Icons.Filled.Edit,
            endIcon = Icons.Filled.Share
        )

        PreferenceItemVariant(
            title = "PreferenceItem变种",
            icon = Icons.Filled.AccountCircle,
