Easy Dev Core #

The foundational layer of the Easy Dev Toolkit. This package provides essential utilities, functional error handling, advanced logging, and responsive helpers that power the rest of the ecosystem.

Features #

1. Functional Error Handling (Result<T, E>) #

Stop using try-catch blocks for expected logic flows. Use Result to explicitly handle success and failure.

import 'package:easy_dev_core/easy_dev_core.dart';

// 1. Return a Result
Result<int, String> divide(int a, int b) {
  if (b == 0) return Result.error('Cannot divide by zero');
  return Result.ok(a ~/ b);
}

void main() {
  final result = divide(10, 2);

  // 2. Handle with match
  result.match(
    (value) => print('Success: $value'),
    (error) => print('Error: $error'),
  );

  // 3. Or check explicitly
  if (result.isSuccess) {
    print(result.unwrap);
  }
}

2. Clean Logger (CleanLogger) #

A leveled logger with emoji support to keep your debug output readable.

CleanLogger.info('App initialized');      // ℹ️ [INFO] App initialized
CleanLogger.debug('User ID: 123');        // 🐛 [DEBUG] User ID: 123
CleanLogger.warning('Battery low');       // ⚠️ [WARN] Battery low
CleanLogger.error('Connection failed',    // ❌ [ERROR] Connection failed
  error: e, 
  stackTrace: s
);

3. Event Transformers (EasyDebounce, EasyThrottle) #

Manage rapid user inputs effortlessly.

final debouncer = EasyDebounce(delay: Duration(milliseconds: 500));

// Call this on every keystroke
void onSearchChanged(String query) {
  debouncer.run(() {
    // API call happens only after 500ms of inactivity
    searchApi(query);
  });
}

4. Responsive & Context Extensions #

Build adaptvie UIs with less boilerplate.

// In build(BuildContext context)
if (context.isTablet) { ... }
if (context.isLandscape) { ... }

// Size config
10.h; // 10% of screen height
20.w; // 20% of screen width
12.sp; // 12 scalable pixels

5. Easy Validator (EasyValidator) #

Build form validation logic with a clean, chainable API.

TextFormField(
  validator: EasyValidator()
    .required()
    .email()
    .minLength(6)
    .build(),
);
