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 ?
