Scene 추가

1. 먼저 SceneID enum을 만들어줍니다.

typedef enum {
    MyAppSceneMain,
} MyAppScene;

2. Scene에 들어올 때, 나올 때, 이벤트를 받았을 떄 호출 될 콜백 함수를 만들어줍니다.

void main_scene_on_enter(void* context) {
    UNUSED(context);
}

void main_scene_on_exit(void* context) {
    UNUSED(context);
}

bool main_scene_on_event(void* context, SceneManagerEvent event) {
    UNUSED(context);
    UNUSED(event);

    return false;
}

3. 기본 코드의 Scene 핸들러 부분에 핸들러를 추가해줍니다.

void (*const app_scene_on_enter_handlers[])(void*) = {
    main_scene_on_enter,
};

void (*const app_scene_on_exit_handlers[])(void*) = {
    main_scene_on_exit,
};

bool (*const app_scene_on_event_handlers[])(void*, SceneManagerEvent) = {
    main_scene_on_event,
};

const SceneManagerHandlers app_scene_event_handlers = {
    .on_enter_handlers = app_scene_on_enter_handlers,
    .on_exit_handlers = app_scene_on_exit_handlers,
    .on_event_handlers = app_scene_on_event_handlers,
    .scene_num = 1,
};

4. view_dispatcher 시작 전에 MainScene을 실행해줍니다.

int32_t my_first_app_app(void* p) {
    UNUSED(p);

    Gui* gui = furi_record_open(RECORD_GUI);
    App* app = app_alloc();

    view_dispatcher_attach_to_gui(app->view_dispatcher, gui, ViewDispatcherTypeFullscreen);

    // HERE
    scene_manager_next_scene(app->scene_manager, MyAppSceneMain);

    view_dispatcher_run(app->view_dispatcher);
    
    app_free(app);
    furi_record_close(RECORD_GUI);

    return 0;
}
