Filament: Show Table Action Only When Filter is Applied

Imagine you have a table Action that you want to show ONLY when a certain filter is applied. For example, let's show the Restore action only when the "Show deleted records" filter is applied.

In the visible() method, we can inject the table from a HasTable and get the status of a filter using the getTableFilterState() method.

use Filament\Tables;
 
Tables\Actions\RestoreAction::make()
    ->visible(fn (Tables\Contracts\HasTable $livewire): bool => $livewire->getTableFilterState('trashed')['value'] === '0'), 

And that's it. Only when a filter is applied will the action be visible.
