Responsive default size

this component uses the 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.
