flutter_call_outcome

Description:

flutter call outcome

function_call_outcome #






This is a dart package inspired by GoLang's response and error parsing functionality at the same time.
This package provide with a datatype that can we used to return data and exception from a function call at the same time.
To provide the flexibility with the datatype of the data field in the object you can strongly couple the object to store a specific type of value by using a TypedConstructor.
🛠Features #

✅ return a data variable and exception from a function at the same time.
✅ make data strongly coupled to store in particular datatype value only.
❌ provide the ability to return multiple parameters which isn't supported in dart.
