## Responsive default size

this component uses the [react-native-pixel-perfect](https://www.npmjs.com/package/react-native-pixel-perfect)

and the defualt style is using base resolution for iphone7, in case you want to use the default design but, using a different base resolution, I added a function called updateBaseResolution(width,height) to use it you need to access it via a ref to the component.

since the component is dependant on react-native-pixel-perfect, when installing this package you install also react-native-pixel-perfect if it's not already installed.

so you can create your own responsive size function and use it to set your custom style.

### notes about props

* **value prop** - this component uses it's own state to hold value if value is not given as a prop
* **style props** - this component has a default style and the styles props are to override the default style or add more fields
* **totalWidth prop** - this prop is for the entire component width, and all other sizes are derived from it , unless given other size props
* **initValue prop** - if using value prop, this is not needed and the initial value can be given by the value prop
* **validateOnBlur** - added on version 1.3.2, if set to false the text input will validate while typing, not recommended, so just keep it true unless there is a good reason not to use the default functionallity 
* **reachMaxIncIconStyle** - added on version 1.4.0, used to set style to the increment button icon in case maxValue is reached - **optional**
* **reachMaxDecIconStyle** - added on version 1.4.0, used to set style to the decrement button icon in case maxValue is reached - **optional**
* **reachMinIncIconStyle** - added on version 1.4.0, used to set style to the increment button icon in case minValue is reached - **optional**
* **reachMinDecIconStyle** - added on version 1.4.0, used to set style to the decrement button icon in case minValue is reached - **optional**
* **onLimitReached** - added on version 1.7.0, used to handle event of min/max reached, **this function receives 2 arguments: (isMas:Boolean, msg:String)** like in the advanced example above - **optional**
* **extraTextInputProps**  - added on version 1.8.0, used to add props used for the original TextInput component that are not used/supported in this component explicitly - **optional**
