Flutter Utils Providers #

A comprehensive Flutter utility package that provides a collection of helper functions for common development tasks including validation, data manipulation, file handling, permissions management, and more.

Features #

• Password Validation: Multi-level password security validation (low, medium, high)
• Data Manipulation: Advanced map and list operations with deep merging capabilities
• JSON Handling: Encoding/decoding utilities for complex JSON structures
• File Operations: File picker integration and file handling utilities
• Permissions: Simplified permission handling across platforms
• Geographic Utilities: Coordinate and location-based helpers
• Date/Time Functions: Comprehensive date formatting and manipulation
• CUIT Validation: Argentine tax identification (CUIT/CUIL) validation
• Mathematical Utilities: Extended math operations and calculations
• Image Processing: Image picker and processing utilities

Installation #

Add this to your package's pubspec.yaml file:

dependencies:
  flutter_utils_providers: ^1.0.0

Then run:

flutter pub get

Usage #

Password Validation #

Validate passwords with different security levels:

import 'package:flutter_utils_providers/flutter_utils_providers.dart';

// Low security: minimum 6 characters
bool isValid = FlutterUtilsProvider.validaPassword(
  NivelSeguridadPassword.bajo,
  'mypass123'
);

// Medium security: minimum 8 characters with letters and numbers
bool isValid = FlutterUtilsProvider.validaPassword(
  NivelSeguridadPassword.medio,
  'MyPassword123'
);

// High security: minimum 8 characters with uppercase, lowercase, numbers, and special characters
bool isValid = FlutterUtilsProvider.validaPassword(
  NivelSeguridadPassword.alto,
  'MyP@ssw0rd!'
);

Data Manipulation #

Work with maps and lists efficiently:

// Deep merge two maps immutably
Map<String, dynamic> merged = FlutterUtilsProvider.deepMergeMapInmutable(
  {'key1': 'value1'},
  {'key2': 'value2'}
);

// Compare two lists
bool areEqual = FlutterUtilsProvider.compararListas(list1, list2);

// Create new map with schema validation
Map<String, dynamic> newMap = FlutterUtilsProvider.newMap(
  esquema: schemaMap,
  mapaOriginal: originalData,
  mapaActualizado: updatedData,
);

JSON Operations #

Handle JSON encoding and decoding:

// Decode JSON safely
Map<String, dynamic> decoded = FlutterUtilsProvider.decodeMapJson(
  jsonString,
  'fieldName'
);

// Encode JSON
Map<String, dynamic> encoded = FlutterUtilsProvider.encodeMapJson(
  dataMap,
  keysToEncode
);

// Validate JSON string
bool isValid = FlutterUtilsProvider.isValidJson(jsonString);

File Operations #

Access file and permission utilities:

import 'package:flutter_utils_providers/flutter_utils_archivos.dart';
import 'package:flutter_utils_providers/flutter_utils_permisos.dart';

// File operations through FlutterUtilsArchivos
// Permission handling through FlutterUtilsPermisos

Date Formatting #

Format dates easily:

import 'package:flutter_utils_providers/flutter_utils_implementacion_func_fecha.dart';

// Use FlutterUtilsImplementacionFuncFecha for date operations

Geographic Utilities #

Work with coordinates and locations:

import 'package:flutter_utils_providers/flutter_utils_implementacion_geo.dart';

// Access geographic calculation utilities

CUIT/CUIL Validation #

Validate Argentine tax identification numbers:

import 'package:flutter_utils_providers/flutter_utils_implementacion_cuit.dart';

// Use FlutterUtilsImplementacionCuit for CUIT/CUIL validation

Additional Features #

The package includes several implementation modules:

• FlutterUtilsArchivos: File handling utilities
• FlutterUtilsPermisos: Permission management
• FlutterUtilsImplementacionFuncFecha: Date/time functions
• FlutterUtilsImplementacionGeo: Geographic utilities
• FlutterUtilsImplementacionCuit: CUIT/CUIL validation
• FlutterUtilsImplementacionTransDestino: Data transformation utilities
