Convert existing Android or IOS spurce of app to Flutter

Job ID: 31092903

Budget: £250 – £750 GBP

I'm looking to convert my existing app to a cross platform language called Flutter

The app is here :
https://play.google.com/store/apps/details?id=uk.co.e2e.orderapp.unitedconnect

I have source coding for IOS and Android both are native.

It is used for customers to place orders.

Ideally looking for a reasonably quick turn around.

If quoting a price, please provide a fixed price, not a price that will be changed later.
