+# swipe_to
+
+SwipeTo is a wrapper for a chat view widget which can be used initiate callback when user horizontally swipe on it.
+
+## Getting Started
+To use this packages, you just simply need to wrap your child component in `SwipeTo` widget and pass a `VoidCallback` that you can carry forward with your task.
+
+In the `pubspec.yaml` of your flutter project, add the following dependency:
+
+```yaml
+dependencies:
+  ...
+  swipe_to: 0.0.1+8
+```
+
+In your library add the following import:
+
+```dart
+import 'package:swipe_to/swipe_to.dart';
+```
+## Parameter Info
+* **``child``** : (@required) `StateLess` or `StateFull` flutter widget.
+* **``onRightSwipe``** : callback which will be initiated at the end of right swipe animation. If not passed right swipe will be disabled
+* **``onLeftSwipe``** : callback which will be initiated at the end of left swipe animation. If not passed left swipe will be disabled
+* **``iconOnRightSwipe``** : IconData that will be displayed on left beneath child widget when swiped right. If not specified default is `Icons.reply`
+* **``rightSwipeWidget``** : Widget that will be displayed beneath child widget when swipe right. If `iconOnRightSwipe` is defined this will have no effect.
+* **``iconOnLeftSwipe``** : IconData that will be displayed on right beneath child widget when swiped left. If not specified default is `Icons.reply`
+* **``leftSwipeWidget``** : Widget that will be displayed beneath child widget when swipe left. If `iconOnLeftSwipe` is defined this will have no effect.
+* **``iconSize``** : Double value defining size of displayed icon beneath child widget. If not specified default it will take **26** 
+* **``iconColor``** : Color value defining color of displayed icon beneath child widget. If not specified `primaryColor` from theme will be taken
+* **``offsetDx``** : Double dx value used in ``Offset()`` till which position of child widget will get animated. If not specified **0.3** default will be taken. onRightSwipe +dx value will be used and for onLeftSwipe -dx value will be used
+* **``animationDuration``** : Duration value to define animation duration. If not specified default is **150 milliseconds**
+
+## Major changes onwards [ver 0.0.1+5]
+* For a single child widget, we can now enable swipe for both left and right direction
+* ``swipeDirection`` parameter is removed. Now ``onLeftSwipe`` and `onRightSwipe` callback will enable swiping for a particular direction if passed
+* ``iconData`` is now split into two parameter, ``iconOnRightSwipe`` & ``iconOnLeftSwipe`` for future use
+* ``endOffset`` is now change to accept a double value only
+* ``callBack`` is now split into two parameter, ``onLeftSwipe`` & ``onRightSwipe``
+
+## Deprecated/Removed Parameters
+* **swipeDirection** : Enum value from [``swipeToLeft``, ``swipeToRight``] only. Make sure to pass relative Offset value according to passed ``swipeDirection`` value. If not specified ``swipeToRight`` will be taken as default.
+* **iconData** : IconData that will be displayed beneath child widget. if not specified default is `Icons.reply`
+* **endOffset** : Offset value till which position of child widget will get animated. if not specified **Offset(0.3, 0.0)** default will be taken
+* **callBack** : (@required) callback which will be initiated at the end of swipe animation
+
+
+**Example** : **SwipeToRight**
+Wrap your desired widget with `SwipeTo` & pass a call to `onRightSwipe` parameter.
+```dart
+SwipeTo(
+    child: Container(
+        padding: const EdgeInsets.symmetric(vertical: 10.0, horizontal: 8.0),
+        child: Text('Hey You! Swipe me right 👉🏿'),
+    ),
+    onRightSwipe: () {
+        print('Callback from Swipe To Right');
+    },
+),
+```
+**Example** : **SwipeToLeft**
+Wrap your desired widget with `SwipeTo` & pass a call to `onLeftSwipe` parameter.
+```dart
+SwipeTo(

+        child: Text('👈🏿 Hey You! Swipe me Left'),
+    ),
+    onLeftSwipe: () {
+        print('Callback from Swipe To Left');
+    },
+),
+```
+
+**Example** : **SwipeToLeft & SwipeToRight** 
+Wrap your desired widget with `SwipeTo` & pass a call to `onLeftSwipe` & `onRightSwipe` parameters.
