How to set the textinput box above the Keyboard while entering the input field in react native

You can use a scrollview and put all components inside the scrollview and add automaticallyAdjustKeyboardInsets property to scrollview.it will solve your problem.

automaticallyAdjustKeyboardInsets Controls whether the ScrollView should automatically adjust its contentInset and
scrollViewInsets when the Keyboard changes its size. The default value is false.

<ScrollView automaticallyAdjustKeyboardInsets={true}>

          {allChildComponentsHere}
         <View style={{ height: 30 }} />//added some extra space to last element
</ScrollView>
