From bc58ce52b636fe5b54c783646191b46f0d31eefd Mon Sep 17 00:00:00 2001 From: Matt Goldman Date: Sat, 4 Oct 2025 17:09:45 +1000 Subject: [PATCH 01/24] Refactor and restructure Plugin.Maui.SmartNavigation - Removed the Resolver and StartupExtensions classes from the Maui.Plugins.PageResolver namespace and integrated them into the Plugin.Maui.SmartNavigation namespace. - Introduced new attributes: IgnoreAttribute, NoAutoDependenciesAttribute, SingletonAttribute, and TransientAttribute for better dependency management. - Implemented MopupExtensions for enhanced popup navigation capabilities. - Added source generators for automatic dependency registration and view model mapping. - Created MarkupExtensions for resolving view models directly in XAML. - Enhanced NavigationExtensions to support both parameterless and parameterized navigation. - Established a new project structure with appropriate project files and dependencies. - Updated Directory.Build.props and Directory.Packages.props for centralized package management. --- .github/workflows/ci.yml | 6 +- Directory.Build.props | 25 +++++++++ Directory.Packages.props | 15 +++++

Added `RouteKind` enum to categorize navigation routes. Enhanced `Route` record with improved `Build` methods: - Supports query strings and dictionary-based parameters. - Constructs URLs with optional query parameters. Added XML documentation for improved code clarity.

Introduced `UseAutoDependenciesAttribute` to replace `NoAutoDependenciesAttribute` for marking classes for auto-dependency registration. Updated `MauiProgram` to use the new attribute. Replaced the `_dependencies` field with a local `dependencies` dictionary, improving code clarity and reducing reliance on class-level state. Enhanced error handling and logging for better diagnostics. Updated source generation logic to use the new `dependencies` dictionary, supporting automatic registration of pages, view models, and services with appropriate lifetimes (`Singleton` or `Transient`). Removed redundant code, including `NoAutoDependenciesAttribute` and the old `Initialize` method. Improved attribute handling with null-safe checks and replaced hardcoded strings with robust logic. General code cleanup for better readability and maintainability. --- src/DemoProject/MauiProgram.cs | 2 + .../NoAutoDependenciesAttribute.cs | 4 - .../UseAutoDependenciesAttribute.cs | 4 + .../AutoDependencies.cs | 216 +++++++++--------- 4 files changed, 113 insertions(+), 113 deletions(-) delete mode 100644 src/Plugin.Maui.SmartNavigation.Attributes/NoAutoDependenciesAttribute.cs create mode 100644 src/Plugin.Maui.SmartNavigation.Attributes/UseAutoDependenciesAttribute.cs diff --git a/src/DemoProject/MauiProgram.cs b/src/DemoProject/MauiProgram.cs index da43d5f..8b58a4f 100644 --- a/src/DemoProject/MauiProgram.cs +++ b/src/DemoProject/MauiProgram.cs @@ -2,9 +2,11 @@ using DemoProject.Popups.ViewModels;
