Flutterda qanday harakatlar bilan ishlash mumkin?

Flutter-da, GestureDetector va boshqa widgetlar yordamida quyidagi harakatlarni boshqarish mumkin:

• Bosishlar:

  • onTap: Oddiy bosish.
  • onDoubleTap: Ikki marta bosish.
  • onLongPress: Uzoq bosish.
  • onTapDown: Ekranga bosilgan vaqtda.
  • onTapUp: Bosishdan so'ng chiqarish.
  • onTapCancel: Bosishni bekor qilish.

• Surish (Draggable):

  • onVerticalDragStart: Vertikal surish boshlanishi.
  • onVerticalDragUpdate: Vertikal surishni yangilash.
  • onVerticalDragEnd: Vertikal surishni yakunlash.
  • onHorizontalDragStart: Gorizontal surishni boshlash.
  • onHorizontalDragUpdate: Gorizontal surishni yangilash.
  • onHorizontalDragEnd: Gorizontal surishni yakunlash.
  • onPanStart: Har qanday surishni boshlash.
  • onPanUpdate: Har qanday surishni yangilash.
  • onPanEnd: Har qanday surishni yakunlash.

• Kattalashtirish/kichraytirish (Scale):

  • onScaleStart: O'lchashni boshlash.
  • onScaleUpdate: O'lchashni yangilash.
  • onScaleEnd: O'lchashni yakunlash.

• Boshqa harakatlar:

  • onForcePressStart: Kuchli bosishni boshlash (ba'zi qurilmalarda qo'llab-quvvatlanadi).
  • onForcePressPeak: Kuchli bosishning cho'qqisi.
  • onForcePressUpdate: Kuchli bosishni yangilash.
  • onForcePressEnd: Kuchli bosishni yakunlash.

GestureDetectordan foydalanish misoli:

import 'package:flutter/material.dart';

class MyGestureWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return GestureDetector(
      onTap: () {
        print('Bosildi!');
      },
      onDoubleTap: () {
        print('Ikki marta bosildi!');
      },
      onLongPress: () {
        print('Uzoq bosildi!');
      },
      child: Container(
        color: Colors.blue,
        width: 100,
        height: 100,
        child: Center(
          child: Text('Menga bos!'),
        ),
      ),
    );
  }
}
