Yaya Flutter ke sarrafa ishara da shigarwar mai amfani?

Question

Accepted Answer

Flutter sarrafa **ishara na taɓawa** (taɓawa, zamewa, ja, pinch) ta hanyar widgets da ke gano ishara kamar **GestureDetector** da **InkWell**, sannan da alamomin jiya-jiya na widget. Fahimtar sarrafan ishara shine mahimmi don gina ƙarfin jiga.

## GestureDetector — gano ishara

```dart
// GestureDetector wraps a widget and detects gestures on it
GestureDetector(
  onTap: () => print('tapped'),
  onDoubleTap: () => print('double tapped'),
  onLongPress: () => print('long pressed'),
  onPanUpdate: (details) => print('dragging: ${details.delta}'),  // drag
  onScaleUpdate: (details) => print('pinch: ${details.scale}'),    // pinch/zoom
  child: Container(width: 100, height: 100, color: Colors.blue),
)
```

`GestureDetector` yana linƙe da widget kuma yana ba da watsun taɓawa, taɓawa biyu, taɓawa mai tsanani, zamewa (pan), alkalami (pinch), da ƙari.

## InkWell — Material taɓawa tare da ripple

```dart
// InkWell — like a tappable area WITH the Material ripple effect (visual feedback)
InkWell(
  onTap: () => doSomething(),
  child: Padding(padding: EdgeInsets.all(16), child: Text('Tap me')),
)
// → use InkWell for Material-style tappable areas (visual feedback); GestureDetector
//   for general gestures without visual effects
```

## Jiya-jiyar hulɗa da kyau matakai

```text
✓ Many widgets handle input themselves: buttons (onPressed), Dismissible (swipe-to-dismiss),
  Draggable/DragTarget (drag-and-drop), InteractiveViewer (pan/zoom), sliders, switches
✓ Use the RIGHT widget — buttons for buttons (not GestureDetector + onTap); InkWell for
  Material feedback; GestureDetector for custom gestures
✓ Provide visual FEEDBACK on interaction (ripples, state changes) for good UX
✓ Mind accessibility (sufficient tap targets, semantics)
```

Fahimtar ishara da shigarwar mai amfani shine mahimmi saboda **ƙarfin jiga ne na hulɗa** — karɓuwar taɓuwan mai amfani (taɓawa, zamewa, ja) shine tushe na aiki na ƙarfin jiga, don haka shi ne lahani na ilmin sana'a.

Ɗarukan wayar hannu suna da rushewa ta hanyar taɓawa, kuma sarrafar ishara ƙaiƙai shine tushe ga gina ƴan hulɗa masu mahimmanci.

Fahimtar **GestureDetector** (linƙe da widgets don gano taɓawa, taɓawa biyu, taɓawa mai tsanani, zamewa, pinch, da ƙari ta hanyar watsun) shine aikin babbar gida don sarrafar ishara ta gida, yana bukar hulɗa masu daidai.

Fahimtar **InkWell** (ba da yankunan taɓawa tare da sakamakon ripple na Material don ba da rahoto) shine mahimmi don hulɗar Material inda rahoto ya imani.

Fahimtar **jiya-jiyar hulɗa na jiya-jiya** (batutuwa tare da onPressed, Dismissible don zamewa-don-bawa-jiya, Draggable/DragTarget don zamewa-da-dip, InteractiveViewer don pan/zoom, sliders, switches) da **kyau matakai na amfani da widget daidai** (batutuwa don batutuwa maimakon GestureDetector + onTap, InkWell don Material rahoto, GestureDetector don ishara masu daidai) yana nuna gina hulɗa daidai, masu komai maimakon sake gina su.

Fahimtar mahimmancin **rahoto na gani** (ripples, canja za'i don kyau karya) da komai (isashen matakinan taɓawa) yana nuna horar hulɗa masu sankatawa.

Saboda ƊarukaN ne na asali na hulɗa (karɓuwa taɓuwan mai amfani shine mahimmi) da Flutter ke sarrafa ishara ta hanyar GestureDetector, InkWell, da widgets na hulɗa na jiya-jiya, da saboda fahimtar waɗannan da amfani da tools daidai shine mahimmi don gina hulɗa masu mahimmanci, masu sankatawa ƊarukaN, fahimtar ishara da shigarwar mai amfani a Flutter shine mahimmi, daidai ana yin amfani da ita - mahimmi na tushe don gina ƴan hulɗa masu mahimmanci da duk ƊarukaN suke bukar, mahimmi don karɓuwar taɓuwan mai amfani ƙaiƙai da gina hulɗa masu komai a duk ƊarukaN na Flutter.
