Blazor Access Dark/Light status


Hi!

Is there any way to access the light/dark/system value of the current user theme inside the c# side? We have some off-the-shelf components that require to know the state (light/dark) so they can fit the same theme - I can only find a function that gets the default not the Current value.

Thanks!
John

Hi,

The current value is stored inside localStorage, you can get current mode by accessing a data-bs-theme localStorage value.

Here is an example:

protected override async Task OnAfterRenderAsync(bool firstRender)

 {

if(firstRender){

var state = await JS.InvokeAsync<string>("localStorage.getItem", "data-bs-theme");

await JS.InvokeVoidAsync("console.log", state);

}

 }


Also, you can use Blazored.LocalStorage package to access localStorage value.
