tauri-plugin-theme

Tauri currently doesn't support dynamically change app theme, this plugin makes up for that.

[!NOTE]
This only applies to the Tauri 2x version. If you are using the Tauri 1x version, please refer to tauri-1x-version.

Install

cargo add tauri-plugin-theme

let mut ctx = tauri::generate_context!();
tauri::Builder::default()
    // Init plugin and auto restore window theme !!!
    .plugin(tauri_plugin_theme::init(ctx.config_mut()))
    // ...
    .run(ctx)
    // ...

Tauri permissions

Add to src-tauri/capabilities/default.json

{
  ...
    "permissions": [
        ...
        "theme:default"
    ]
}

Usage

// Follow system theme setting
invoke("plugin:theme|set_theme", {
  theme: "auto",
});

// Always use light theme
invoke("plugin:theme|set_theme", {
  theme: "light",
});

// Always use dark theme
invoke("plugin:theme|set_theme", {
  theme: "dark",
});

// Get saved theme (default: auto)
const theme = await invoke("plugin:theme|get_theme");

When you call set_theme, the theme will be auto saved, and it will be restored auto after the App restart.
