2d-inc/HistoryOfEverything

This system is a cross-platform mobile application designed for exploring historical and scientific knowledge through an interactive timeline. It allows users to browse eras, search for specific topics, and read detailed articles with markdown support. The app features animated character interactions, a favorites management system for saving content, and a unified codebase supporting both Android and iOS platforms.

A new FavoritesBloc class has been introduced to handle the logic for storing, retrieving, and persisting user favorites. This component manages a list of TimelineEntry objects, utilizing the shared\_preferences library to save and load favorites across app restarts. It provides methods to add and remove favorites, automatically sorting them by start time, and ensures data is persisted to disk.

Added a new 'full\_quality' directory containing over 30 new text files in the 'Articles' subdirectory. These files provide detailed, high-quality encyclopedic content on a wide range of topics, including history (e.g., World War I, Cold War), science (e.g., Big Bang, Dinosaurs), biographies (e.g., Marie Curie, Nelson Mandela), and general knowledge (e.g., Animals, Internet). This expands the available reference material for users seeking in-depth information.

Introduced new controller classes to enable touch-based interactivity for animated characters in the Amelia and Newton article pages. The diff adds \FlareInteractionController\ and \NimaInteractionController\ abstract base classes, along with concrete implementations (\AmeliaController\ and \NewtonController\) that handle touch input to drive specific animation nodes (face elements and tree trunk, respectively). This change implements the logic required to map user touch coordinates to in-game object movements, allowing users to interact with the animations on these specific pages.

The app now includes a new set of informational articles covering topics such as the Big Bang, dinosaurs, World War I and II, and various historical figures and events. These articles provide deeper context for the timeline, allowing users to read about specific events and subjects directly from the app.

The app now displays articles using a new ArticleWidget that renders markdown content via the flutter\_markdown package. The view includes a header with title and subtitle, a scrollable column containing the TimelineEntryWidget for interactive animations, and the formatted article text. The widget also supports favoriting articles and handles device padding for proper layout.

The Android portion of the app has been initialized with standard Flutter scaffolding, including the AndroidManifest.xml defining the app package, launcher activity, and internet permissions, alongside the MainActivity Java class that registers Flutter plugins. A white launch splash screen and corresponding styles are configured, and the project is set up with Gradle 4.4 for the Android build system.

Users can now browse a fully interactive timeline featuring animated assets (Flare and Nima), clickable bubbles that navigate to article pages, and a favorites sidebar. The timeline dynamically adjusts its background colors and header styling based on the current era, and supports pinch-to-zoom, long-press zooming, and smooth scrolling with momentum.

The app now features a main menu with three expandable sections, each containing links to timeline entries. A search bar allows users to find specific events, with results displayed as a list of thumbnails and titles. Users can also view their saved favorites, which are stored in the app's state. The about page provides information about the app, including links to the developers and tools used. Additionally, the main menu includes a share button and a favorites button that navigates to the favorites page.

The application now initializes with a \BlocProvider\ that loads the timeline data and favorites state, making them accessible throughout the widget tree. A new \SearchManager\ is introduced, which pre-processes all timeline entry labels into a substring index to enable efficient search queries. Additionally, a \colors.dart\ file defines the app's visual theme, including specific colors for text, background, and the favorites gutter accent.

The iOS native project files for the app have been added, including the main entry point, application delegate, and storyboard layouts. The app's display name is set to 'History' in the Info.plist, and the app icon assets are configured for iPhone and iPad across multiple resolutions.

app/ios/Runner · high confidence

The iOS build configuration files (AppFrameworkInfo.plist, Debug.xcconfig, Release.xcconfig) and the Xcode workspace structure (contents.xcworkspacedata, WorkspaceSettings.xcsettings) have been added to the app directory. These changes establish the necessary metadata and build settings for the Flutter iOS target, ensuring the app can be built and linked with its dependencies.

The iOS project configuration has been updated, including the addition of a profile build target and adjustments to the Xcode scheme for building and archiving the Runner application.

Added a new widget test file (widget\_test.dart) containing a basic empty test case using the Flutter WidgetTester utility, establishing the foundation for future widget interaction tests.

The project now includes Flare and Nima as submodules, enabling the use of Flare and Nima animation libraries in the Flutter application. This allows for the integration of vector animations and interactive graphics into the app's UI.

dependencies · high confidence

This change introduces the foundational build configuration for the Android and iOS platforms, along with the Dart package dependencies for the application. It adds the \app/android/app/build.gradle\ and \app/android/build.gradle\ files to configure the Android build system, including SDK versions and dependencies like JUnit and Espresso for testing. For iOS, it adds a \Podfile\ to manage CocoaPods dependencies, specifically linking Flutter and plugin pods. The \app/pubspec.yaml\ file defines the app's metadata, including the \nima\ and \flare\_flutter\ libraries for animations, as well as other dependencies like \flutter\_markdown\, \share\, and \url\_launcher\. Additionally, it includes the \tools/pubspec.yaml\ and \tools/pubspec.lock\ files, which specify the \image\ package and its transitive dependencies.
