Implementing .NET MAUI Shimmer (SfShimmer)

SfShimmer displays an animated shimmer placeholder while content loads in the background, improving perceived app responsiveness. It supports 7 built-in layout types, fully custom views using ShimmerView shapes, and extensive wave animation customization.

When to Use This Skill

Use this skill when users need to:

• Add a loading placeholder before data or content is fetched
• Show a skeleton screen while an API call completes
• Replace a spinner with a content-shaped loading animation
• Customize shimmer colors, wave direction, or animation speed
• Build a custom shimmer layout that mirrors your actual UI

Component Overview

The SfShimmer control provides:

• Built-in Layout Types: 7 pre-designed shimmer patterns (CirclePersona, SquarePersona, Profile, Article, Video, Feed, Shopping)
• Custom View Support: Build custom shimmer layouts using ShimmerView with Circle, Rectangle, and RoundedRectangle shapes
• Wave Animation Control: Configurable wave direction (5 options), width, and animation duration
• Color Customization: Independent Fill (background) and WaveColor (highlight) properties
• Repeat Patterns: RepeatCount property for vertical stacking of shimmer layouts
• Content Toggle: IsActive property for seamless switching between shimmer and loaded content
• Flexible Integration: Works with any .NET MAUI View as child content
• Performance Optimized: Lightweight animation that improves perceived app responsiveness
