avatar_fallback 0.1.0

A Flutter avatar widget with a reliable fallback chain: any ImageProvider down to deterministic, grapheme-safe initials that never fail.

0.1.0

Initial release.

• AvatarFallback widget with a convenience constructor (image + initials fallback) and an AvatarFallback.sources constructor for an explicit priority chain.
• AvatarSource sealed hierarchy: ImageAvatarSource, NetworkAvatarSource, AssetAvatarSource, IconAvatarSource, WidgetAvatarSource.
• Support for any ImageProvider (network, asset, memory, file, or a pluggable cache such as CachedNetworkImageProvider).
• Stable, deterministic background colors from names using an FNV-1a hash (not String.hashCode), with automatic contrasting text color.
• Unicode-correct, grapheme-safe initials that handle emoji, combining marks and RTL names.
• AvatarShape sealed type: circle, square, and rounded(radius).
• AvatarGroup with overlap control and a customizable +N overflow indicator.
• Badge slot, accessibility semantics, and image fade-in.
• Material 3 theming via AvatarFallbackTheme (ThemeExtension).
• Zero heavy dependencies; works on Android, iOS, web, macOS, Windows and Linux.
