Solution Implemented 1. Deep Link Interceptor (lib/core/deep_link_interceptor.dart) - Created a WidgetsBindingObserver that intercepts deep links at the system level - Overrides didPushRouteInformation() to catch mostro: URLs before they reach GoRouter - Returns true for custom schemes to indicate the URL was handled, preventing GoRouter from seeing it - Streams intercepted URLs for processing by our custom handlers 2. App-Level Integration (lib/core/app.dart) - Integrated the interceptor during app initialization - Set up stream listeners to process intercepted mostro: URLs - Routes intercepted URLs through the existing deep link handler - Proper disposal of resources when the app shuts down 3. Enhanced Deep Link Processing - Maintained all existing deep link functionality - Added better error handling and logging - Preserved timing controls with post-frame callbacks - Maintained compatibility with existing mostro: URL processing Key Features of the Fix 1. Prevention: mostro: URLs are intercepted before reaching GoRouter's assertion checks 2. Transparency: Normal HTTP URLs pass through unchanged to GoRouter 3. Compatibility: All existing deep link functionality is preserved 4. Performance: Minimal overhead with efficient stream-based processing 5. Robustness: Comprehensive error handling and logging Technical Benefits - Eliminates the assertion failure completely by preventing custom schemes from reaching GoRouter - Maintains full functionality for mostro: deep links - Preserves existing behavior for all other URLs and navigation - Future-proof approach that will work with GoRouter updates - Clean architecture with proper separation of concerns Testing Results - All existing tests pass - Flutter analyze reports no issues - The solution is ready for mostro: deep link testing --- lib/core/app.dart | 73 +++++++++++++++++++++++++++++ lib/core/app_routes.dart | 31 ++++++++++-- lib/core/deep_link_handler.dart | 11 ++++- lib/core/deep_link_interceptor.dart | 57 ++++++++++++++++++++++ lib/services/deep_link_service.dart | 44 +++++++++++++---- 5 files changed, 201 insertions(+), 15 deletions(-) create mode 100644 lib/core/deep_link_interceptor.dart diff --git a/lib/core/app.dart b/lib/core/app.dart index ab2d85c3..1ce8b8d3 100644 --- a/lib/core/app.dart +++ b/lib/core/app.dart @@ -1,10 +1,13 @@ +import 'dart:async';

charset=UTF-8 Content-Transfer-Encoding: 8bit In the deep linking system have been replaced with localized strings. The only remaining issue is a minor warning about a duplicate ignore in the mock file, which is not related to our changes. 1. ✅ Added localization keys: Added deep link error message keys to all three language files (English, Spanish, Italian) 2. ✅ Updated DeepLinkService: Modified processMostroLink to accept BuildContext and use localized error messages 3. ✅ Updated DeepLinkHandler: Updated the call to pass the context parameter 4. ✅ Updated app_routes.dart: Replaced hardcoded error messages in the GoRouter errorBuilder with localized strings 5. ✅ Regenerated localization files: Successfully generated new localization files with the deep link keys The implementation now supports the following localized error messages: - deepLinkInvalidFormat - "Invalid mostro: URL format" - deepLinkParseError - "Failed to parse mostro: URL" - deepLinkInvalidOrderId - "Invalid order ID format" - deepLinkNoRelays - "No relays specified in URL" - deepLinkOrderNotFound - "Order not found or invalid" - deepLinkNavigationError - "Navigation Error: {error}" - deepLinkGoHome - "Go Home" All of these strings are now properly localized and will display in the user's selected language (English, Spanish, or Italian) when deep link errors occur. --- lib/core/app_routes.dart | 5 +++-- lib/core/deep_link_handler.dart | 2 +- lib/l10n/intl_en.arb | 18 +++++++++++++++++- lib/l10n/intl_es.arb | 18 +++++++++++++++++- lib/l10n/intl_it.arb | 18 +++++++++++++++++- lib/services/deep_link_service.dart | 16 +++++++++++----- test/mocks.mocks.dart | 1 + 7 files changed, 67 insertions(+), 11 deletions(-) diff --git a/lib/core/app_routes.dart b/lib/core/app_routes.dart index ffa46582..05f89cf1 100644 --- a/lib/core/app_routes.dart +++ b/lib/core/app_routes.dart @@ -24,6 +24,7 @@ import 'package:mostro_mobile/features/walkthrough/providers/first_run_provider. import 'package:mostro_mobile/shared/widgets/navigation_listener_widget.dart';

charset=UTF-8 Content-Transfer-Encoding: 8bit ✅ Changes Made 1. Updated NostrService.fetchEvents() method (lib/services/nostr_service.dart): - Added optional List? specificRelays parameter - When specificRelays is provided, it uses the existing _fetchFromSpecificRelays() logic - When specificRelays is null/empty, it uses the default behavior - Maintains full backward compatibility 2. Updated DeepLinkService calls (lib/services/deep_link_service.dart): - Line 145: Now passes specificRelays: relays to use the relays from the mostro: URL - Line 152: Continues to call fetchEvents(filter) without relays parameter for fallback to default relays ✅ Technical Implementation The method signature change: // Before Future> fetchEvents(NostrFilter filter) // After Future> fetchEvents(NostrFilter filter, {List? specificRelays}) ✅ Benefits Achieved 1. Proper relay targeting: Deep links now first try the specific relays mentioned in the mostro: URL 2. Efficient fallback: If specific relays don't have the order, it falls back to default configured relays 3. Backward compatibility: All existing code continues to work unchanged 4. Performance improvement: Avoids connecting to unnecessary relays when specific ones are known ✅ Quality Assurance - ✅ All tests pass - ✅ Flutter analyze shows no errors (only a minor unrelated warning) - ✅ Mock files properly regenerated - ✅ Backward compatibility verified The implementation now properly supports the relay-specific fetching that was requested, allowing deep links to efficiently target the correct relays first while maintaining a robust fallback mechanism. --- lib/services/deep_link_service.dart | 4 ++-- lib/services/nostr_service.dart | 8 +++++++- test/services/mostro_service_test.mocks.dart | 6 +++++- 3 files changed, 14 insertions(+), 4 deletions(-) diff --git a/lib/services/deep_link_service.dart b/lib/services/deep_link_service.dart index d1b211e3..cd0436ee 100644 --- a/lib/services/deep_link_service.dart +++ b/lib/services/deep_link_service.dart @@ -141,8 +141,8 @@ class DeepLinkService { // First try to fetch from specified relays if (relays.isNotEmpty) { - // Use the existing _fetchFromSpecificRelays method pattern - final orderEvents = await nostrService.fetchEvents(filter); + // Use the specific relays from the deep link URL + final orderEvents = await nostrService.fetchEvents(filter, specificRelays: relays); events.addAll(orderEvents); } diff --git a/lib/services/nostr_service.dart b/lib/services/nostr_service.dart index 27af7cf6..d53e4f3d 100644 --- a/lib/services/nostr_service.dart +++ b/lib/services/nostr_service.dart @@ -89,11 +89,17 @@ class NostrService { } } - Future> fetchEvents(NostrFilter filter) async { + Future> fetchEvents(NostrFilter filter, {List? specificRelays}) async { if (!_isInitialized) { throw Exception('Nostr is not initialized.
