Срыв флаттера contact_picker на android

Question

Кажется, я не могу понять это.

Я добавил разрешение на чтение контактов в мой android / app / src / main / AndroidManifest. xml

<uses-permission android:name="android.permission.READ_CONTACTS"/>

Я тоже с помощью license_handler

    bool status = await Permission.contacts.request().isGranted;

    if (status) {
     Contact contact = await _contactPicker.selectContact();
     //get contact info
    }

отображается экран контактов, но как только я выбираю контакт, приложение вылетает.

вот журналы сразу после касания контакта.
