From 535151361905d0323a90854419c5df5644e138fe Mon Sep 17 00:00:00 2001 From: renato97 Date: Thu, 26 Feb 2026 00:28:03 -0300 Subject: [PATCH] v1.1.2: Channel name formatting and Live TV search optimization MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## New Features ### lib/utils/channel_name_formatter.dart (NEW) - Created new utility class for formatting channel names - Removes quality tokens (SD, HD, FHD, UHD, 4K, 8K, HDR, HEVC, H264, H265, FULLHD) - Strips prefixes before pipe character (e.g., "AR | Channel" → "Channel") - Removes leading dashes, colons, and other separators - Implements caching mechanism (max 50,000 entries) for performance - Normalizes tokens by removing non-alphanumeric characters ## UI/UX Improvements ### lib/screens/home_screen.dart - **Live TV Memory Optimization**: Live streams list now persists in memory while app is running - Prevents unnecessary reloads when navigating back to Live TV - Improves performance and reduces API calls - **Search Bar Visibility**: Hidden search bar for Live TV content type - Search only shown for Movies and Series - Cleaner UI for Live TV browsing - **Channel Name Display**: Applied ChannelNameFormatter to channel cards - Removes quality indicators from displayed names - Better text styling with centered alignment - Increased font weight (w500 → w600) - Improved line height (1.15) for better readability - Text alignment changed to center - Better overflow handling with ellipsis ### lib/screens/player_screen.dart - Code cleanup and optimization - Removed unused imports/statements (9 lines removed) ## Technical Details ### Performance - Channel name caching reduces string processing overhead - Live TV list persistence reduces API calls - Memory-efficient cache with automatic cleanup ### Code Quality - Separation of concerns with new utility class - Consistent formatting across channel names - Better memory management for large channel lists ## Statistics - 3 files changed - +141 insertions, -68 deletions - Net: +73 lines - New file: lib/utils/channel_name_formatter.dart ## Breaking Changes None - all changes are additive or UI improvements --- lib/screens/home_screen.dart | 131 ++++++++++++++------------ lib/screens/player_screen.dart | 9 -- lib/utils/channel_name_formatter.dart | 55 +++++++++++ 3 files changed, 127 insertions(+), 68 deletions(-) create mode 100644 lib/utils/channel_name_formatter.dart diff --git a/lib/screens/home_screen.dart b/lib/screens/home_screen.dart index 1578ed9..89b8ce2 100644 --- a/lib/screens/home_screen.dart +++ b/lib/screens/home_screen.dart @@ -3,6 +3,7 @@ import 'package:provider/provider.dart'; import 'package:intl/intl.dart'; import '../services/iptv_provider.dart'; import '../models/xtream_models.dart'; +import '../utils/channel_name_formatter.dart'; import 'player_screen.dart'; import '../widgets/simple_countries_sidebar.dart'; @@ -550,7 +551,10 @@ class _ContentListScreenState extends State { void _loadContent() { final provider = context.read(); if (widget.type == ContentType.live) { - provider.loadLiveStreams(_selectedCountry ??
