 Let's skip the obvious.

1. InteractiveViewer – Zoom & Pan with Zero Effort

Add pinch-zoom and drag to any widget like images, charts, custom canvases with no extra packages.

InteractiveViewer(
  panEnabled: true,
  minScale: 0.5,
  maxScale: 4,
  child: Image.network(imageUrl),
);

Why it's a gem: Instantly adds pinch gestures that would normally take dozens of lines.

2. SliverAnimatedList

Like AnimatedList, but sliver-friendly for custom scroll views.

SliverAnimatedList(
  key: listKey,
  itemBuilder: (context, index, animation) =>
      FadeTransition(opacity: animation, child: buildItem(index)),
);

Why: Perfect for chat apps or dynamic feeds without reinventing scroll physics.

3. BackdropFilter – Glassmorphism in One Line

Blur anything behind your widget for that iOS-style frosted effect.

BackdropFilter(
  filter: ImageFilter.blur(sigmaX: 8, sigmaY: 8),
  child: Container(color: Colors.white.withOpacity(0.2)),
);

Why: Native blur + transparency with zero third-party packages.

4. CustomScrollView + SliverFillRemaining-Flexible Layout Filler

Keep a bottom button pinned while content scrolls above it.

CustomScrollView(
  slivers: [
    SliverList(delegate: SliverChildListDelegate(children)),
    SliverFillRemaining(hasScrollBody: false, child: BottomSection()),
  ],
);

Why: No more hacky Expanded tricks to push footers down.

5. RawMagnifier – iOS-Style Text Selection Bubble

Introduced in Flutter 3, it shows a system-style magnifier anywhere.

RawMagnifier(
  magnificationScale: 1.5,
  child: TextField(),
);

Why: Adds native-feeling selection for custom editors or drawing apps.

6. AnimatedPositionedDirectional – RTL-Friendly Animations

Like AnimatedPositioned, but respects text direction automatically.

AnimatedPositionedDirectional(
  start: show ? 0 : -200,
  duration: Duration(milliseconds: 300),
  child: Sidebar(),
);

Why: Saves painful logic when supporting both LTR and RTL languages.

7. ShaderMask – Gradient Magic Anywhere

Apply custom shaders (gradients, blend modes) to any child.

ShaderMask(
  shaderCallback: (bounds) => LinearGradient(
    colors: [Colors.purple, Colors.blue],
  ).createShader(bounds),
  blendMode: BlendMode.srcATop,
  child: Icon(Icons.star, size: 80),
);

Why: Eye-catching effects with just a few lines of code.
