afterStateHydrated behavior within Block builder

I have an TextInput field within a Block, and I would like to fill it with uuid when it's empty. I am doing that:

Forms\Components\TextInput::make('internal')
                        ->afterStateHydrated(function ($component, $state) {
                            if (! $state) {
                                $component->state(Str::uuid()->toString());
                            }
                        })
                        ->disabled()
                        ->suffixAction(CopyAction::make())
                        ->dehydrateStateUsing(fn ($state) => $state ?? Str::uuid()->toString()),

But it's not working. Any thoughts?

Should work. Did you try only this?

Forms\Components\TextInput::make('internal')
    ->afterStateHydrated(function (TextInput $component, $state) {
        if (blank($state)) {
            $component->state(Str::uuid()->toString());
        }
    })

Forms\Components\TextInput::make('internal')
    ->afterStateHydrated(function (TextInput $component, $state) {
        if (blank($state)) {
            $component->state(Str::uuid()->toString());
        }
    })

maybe just default() ? that will get filled when the block is created

I am wondering if I will always have the same uuid ?

Dan Harrin•15mo ago

if its in the livewire state yes

does not change anything. It's strange because $state is null when I add a new block but it seems that $component->state(Str::uuid()->toString()); does nothing
