Reactivity 2.0

[lee-to]

Almost all fields support reactivity except:

• Json is not in object mode
• BelongsToMany with AsyncSearch
• RelationRepeater
• HasMany/HasOne/MorphTo

Also in custom fields it is now possible to configure reactivity support, turn it off or specify how exactly to prepare and receive values:

public function isReactivitySupported(): bool;

public function prepareReactivityValue(mixed $value, mixed &$casted, array &$except): mixed;

public function getReactiveValue(): mixed;

Reactive Template example:

Template::make("Template")->fields([
    Text::make('Title'),
])->changeFill(fn($data, Template $ctx) => data_get($data, 'template'))->changeRender(
    fn($value, Template $ctx) => new FieldContainer(
        field: $ctx,
        slot: FieldsGroup::make($ctx->getPreparedFields())->render(),
    ),
)->reactive(),
