Flutter Screenutil

flutter_screenutil est un framework d'interface utilisateur réactif et un outil de mise en page adaptatif pour Flutter. Il fournit un système pour mettre à l'échelle les dimensions de mise en page et les polices en fonction d'un design de référence afin d'assurer des proportions cohérentes sur différentes résolutions d'écran et appareils.

La boîte à outils fonctionne comme un fournisseur de métriques d'écran qui récupère les propriétés de l'appareil en temps réel, notamment la largeur, la hauteur, la densité de pixels et les dimensions de la zone de sécurité (safe area). Elle gère spécifiquement l'adaptation de la mise en page lors des changements d'orientation de l'appareil et des mises à jour du mode écran partagé.

Le framework couvre la gestion adaptative de la typographie, la mise à l'échelle des dimensions de mise en page et la surveillance des métriques d'écran. Il inclut des mécanismes pour contrôler les reconstructions d'interface utilisateur lors du redimensionnement de l'écran et applique des limites de mise à l'échelle pour maintenir l'intégrité visuelle sur de très grands ou très petits écrans.

Features

  • Reference-Based Scaling - Calculates widget sizes by multiplying design-draft dimensions by a ratio derived from the current screen size.
  • Responsive UI Design - Scales widgets and layouts based on design drafts to ensure consistent proportions across different screen resolutions.
  • Multi-Device Layout Adapters - Handles screen size changes and orientation shifts to ensure the UI fits various mobile device screens.
  • Layout Scaling Utilities - Calculates widget sizes and radii based on reference designs to ensure consistent proportions across resolutions.
  • Responsive UI Frameworks - Provides a toolkit for scaling layout dimensions and fonts in Flutter based on a reference design.
  • Screen Metadata Retrieval - Provides programmatic access to real-time device properties such as screen width, height, and pixel density.
  • Adaptive Typography Tools - Automatically adjusts font sizes based on screen dimensions and system zoom settings to maintain readability.
  • Font Size Range Clampers - Scales text sizes based on screen metrics while applying minimum and maximum pixel bounds to prevent extreme sizing.
  • Device Metrics Retrieval - Provides real-time retrieval of screen width, height, pixel density, and safe area dimensions to drive responsive layout scaling.
  • Screen-Metric Based Font Scaling - Scales text based on screen dimensions and system zoom settings using defined minimum and maximum bounds.
  • Layout Recalculation Triggers - Listens to system-level screen change notifications to trigger layout recalculations during orientation or window shifts.
  • Adaptive UI Layouts - Adjusts UI proportions and font sizes automatically during device orientation changes or split-screen mode updates.
  • Safe Area Metrics - Retrieves precise device-specific inset values, including notches and system padding, to calculate usable screen area.
  • Split-Screen Layout Adaptation - Adjusts UI dimensions and layout calculations in real time when the application is used in split-screen mode.
  • Screen Dimension Monitors - Detects changes in screen dimensions to trigger layout updates during device orientation or split-screen transitions.
  • Rebuild Optimization Tools - Limits widget tree updates during screen resizing by defining rebuild factors to optimize performance.
  • UI Element Scaling Constraints - Implements scaling limits to maintain visual integrity on extremely large or small displays.
