Setting default value for Checkbox (forms) is not working

[queen mantle]

I am trying to set a default value for a Checkbox. Basically I am trying to get a value from the database and then based on a specific condition, check/uncheck the box automatically.

Here is the code snippet:

Checkbox::make('subscription_never_ends')
                    ->label('Subscription never ends')
                    ->reactive()
                    ->default(function (OfflinePayment $record) {
                        $stripeId = 'offline_' . $record->transaction_id;
                        $subscription = DB::table('subscriptions')
                            ->where('stripe_id', $stripeId)
                            ->first();

                        Log::info($subscription);

                        return $subscription && $subscription->ends_at === null;
                    })

Are you using form builder in a custom livewire component? Did you add $this->form->fill() in the mount method?

Note that these defaults are only used when the form is loaded without existing data

No. I was doing it inside the public static function form(Form $form): Form inside the resource

So, what to do if I want to set the value based on some saved user value?

For example, if $record->value > 5, check the checkbox, else uncheck
