Javob: https://t.iss.one/dartuzb_faq/36 bundan oldingi postda ham shu savol berildi. Javoblarni o'qib chiqing.

Mobile app va server rest api(json) ya'ni ma'lum bir kelishilgan ma'lumot almashish qoidasi asosida ishlaydi. Serverdagi ma'lumotlarni to'g'ridan to'g'ri ololmaysiz, backend sizga siz so'ragan so'rov asosida javob qaytaradi.

Rest api bilan ishlaydigan packagelar bor maxsus http, dio, retrofit packagelar bor (For, while, do while bir xil maqsad uchun lekin turlicha yo'l bilan ishlaydi)

Dio ham shu packagelardan biri va mashxurrog'i. Pub devdan dio dokunmentatsiyasida batafsil qo'llanmasi bor ishlatish bo'yicha.

Assalamu alaykum,
PinField va Screen Custom Keyboarddan foydalanyapman.
PinFieldlar hammasi fill qilingandan keyin, fielddan focus yo'qoladi.

Fieldda focus yo'q holatda backspace ishlamaydi, pinFieldga bir marta bosib, keyin ishlatish mumkin.

Backspacega bosilganda, focusNode orqali fieldga requestFocus() qilishga harakat qildim, lekin bu function return qilgani uchun, undan _backspace() funksiyasi ishlamay qolyabdi.
Shunga qanday yechim qilsa bo'ladi ?
Yoki boshqa yo'llari ham bormi ?
