Problem description

The documentation indicates that the Filament\Forms\Component\Builder::blockPickerColumns() method should be able to accept a function to dynamically calculate the number of columns. However the method only accepts array, int, or null types as its argument.

If you pass in a Closure as the argument then this results in a TypeError being thrown.

Expected behavior

According to the documentation, the method should accept a Closure that can be used to determine the number of columns.

Steps to reproduce

Create a builder and pass in a Closure as the argument for the blockPickerColumns() method.

Builder::make('test')
    ->blocks([
        Builder\Block::make('text')
            ->schema([
                TextInput::make('test_input')
                    ->label('Text Input'),
            ])
    ])
    ->blockPickerColumns(function() {
        return 2;
    });
