tie_fp 0.0.2

Functional Opinionated library for Flutter

Tie FP

A simple package that provides a class Result along with its subclasses Success and Failure. This package is designed to handle success and failure scenarios in a concise and type-safe manner.

Usage

Here's an example of how you can use the Result package:

import 'package:tie_fp/tie_fp.dart';

void main() {
  Result<int> result = performOperation();

  if (result.isError()) {
    print('An error occurred: ${result.getError()}');
  } else {
    int value = result.getValue()!;
    print('Operation successful! Result: $value');
  }
}

Result<int> performOperation() {
  // Perform some operation that may succeed or fail
  if (operationSucceeded) {
    return Success(42);
  } else {
    return Failure('An error occurred');
  }
}

T tryCatchExample<T>(){
    try{
        var result=performOperationThatMayThrowException();
        return Success(result);
    }catch (e){
        return Failure(e);
    }
}

By using the methods provided by the Result class, you can easily handle success and failure cases without resorting to exceptions or error codes. This promotes a more expressive and safer coding style.

Conclusion

The Result package simplifies the handling of success and failure scenarios by providing a sealed class that encapsulates the result and error information. It enables you to write cleaner and more robust code when dealing with operations that can succeed or fail.
