  • All methods return bool indicating success/failure
  • Prevents the common Flutter error: "setState() called after dispose()"
  • Includes proper exception handling with debug logging
  • Works with any State<T> class through extension methods

• Widget Extensions Structure: New organized extension structure

  • lib/src/extensions/widget/state_extensions.dart - State utility extensions
  • lib/src/extensions/widget/widget.dart - Widget extensions barrel file
  • Updated main extensions export to include widget utilities

Changed #

  • Added practical usage examples with StatefulWidget
  • Documented all available setState safety methods
  • Updated features list to highlight setState safety utilities
  • Improved quick start guide with widget state management examples

Technical Features #

Removed #

• Interface Classes: Removed abstract interface classes that were not core to the package functionality
  • AppLogger - Application logging interface with debug, info, warning, and error methods
  • ConnectivityService - Network connectivity management interface with internet reachability checks
  • interfaces.dart - Export file for interface classes
  • Complete removal of lib/src/interfaces/ directory

Changed #

• Library Exports: Updated main library file (flutter_shared_utilities.dart)
  • Removed export 'src/interfaces/interfaces.dart'; statement
  • Streamlined package to focus on core utilities, extensions, models, and utils

Migration Notes #

• Breaking Change: Applications using AppLogger or ConnectivityService interfaces will need to implement their own logging and connectivity abstractions
• Rationale: Removed interface classes to keep the package focused on concrete utilities rather than abstract contracts
• Alternative: Users can copy the interface definitions from version 1.0.3 if needed, or implement their own logging/connectivity abstractions
• No impact on core functionality: extensions, models, parsers, and utility functions remain unchanged

Fixed #

• SafeParser Double-Encoding Issue: Fixed critical bug where safeEncodeJson() would double-encode already valid JSON strings
  • Before: SafeParser.safeEncodeJson('"hello"') → "\"hello\"" (double quotes)
  • After: SafeParser.safeEncodeJson('"hello"') → "hello" (correct single encoding)
  • Intelligent JSON detection prevents double-encoding of JSON objects, arrays, and primitives
  • Enhanced _isValidJson() helper method with comprehensive validation
  • Improved fallback logic for malformed JSON strings

Added #

• Comprehensive Test Coverage: Added extensive test suites with 78+ new tests

  • test/utils/safe_parser_test.dart - 26 tests covering all SafeParser functionality
  • test/extensions/map/map_parser_extensions_test.dart - 52 tests for MapParserExtensions
  • Round-trip encoding/decoding verification tests
  • Edge case testing (unicode, special characters, deeply nested structures)
  • Error handling and fallback behavior validation
  • Double-encoding prevention verification tests

• Enhanced SafeDecodeJson: Improved JSON decoding with better error handling

  • Smart detection of already-decoded primitive values
  • Enhanced fallback logic for malformed JSON
  • Better handling of quoted strings with escape sequences
  • Graceful return of original string when JSON parsing fails

Changed #

• Type Safety Improvements: Enhanced type annotations in test files
  • More specific type expectations (List<Object?> instead of List)
  • Better type checking in map parser extension tests
  • Improved null safety handling throughout tests

Technical Details #

• JSON Detection Algorithm: New intelligent JSON validation

  • Detects JSON objects ({} format)
  • Detects JSON arrays ([] format)
  • Detects JSON strings (quoted format)
  • Detects JSON primitives (numbers, booleans, null)
  • Validates actual JSON parseability, not just format

• Test Architecture: Following Flutter best practices

  • Grouped tests by functionality for better organization
  • Comprehensive edge case coverage including unicode and special characters
  • Safe type checking without null force operators or unsafe casting
  • Bounds checking for array access in all test scenarios

Migration Notes #

• No breaking changes - all existing functionality preserved
• SafeParser now correctly handles already-encoded JSON without modification
• Enhanced error handling provides better fallback behavior
• Existing code will benefit from the double-encoding fix automatically

Added #

• Enhanced Serialization Extensions: Major improvements to fromSerializable<T>() method

  • List<DateTime> support - Convert arrays of ISO strings, timestamps, and DateTime objects
  • List<Duration> support - Convert arrays of microsecond integers, strings, and Duration objects
  • Map<String, DateTime> support - Handle JSON objects with date fields
  • Map<String, Duration> support - Handle configuration objects with time values
  • Early error detection with assert() statements in debug mode
  • Comprehensive type validation with _isSupportedType() helper method

• Safe Conversion Helpers: New helper methods for robust type conversion

  • _safeDateTime() - Handles ISO strings, timestamps, with Unix epoch fallback

• Improved Type Safety: Enhanced type checking and conversion

  • Fixed string-to-int conversion to handle decimal strings like "95.5" → 95
  • Better handling of mixed data types in collections
  • More robust JSON string parsing for typed collections

Fixed #

• Type casting issues with Map<String, DateTime> and Map<String, Duration>
• Decimal string parsing in _safeInt() method (e.g., "95.5" now converts to 95)
• Eliminated runtime UnsupportedError throws in favor of development-time asserts
