5 Flutter UI Components I Built So You Don't Have To

#flutter #opensource #dart #mobile

After building several Flutter apps, I kept
rebuilding the same UI components from scratch
every single time.

Onboarding screens. Chat bubbles. Pricing pages.
Product grids. Feed screens.

So I decided to properly package them as clean,
standalone .dart files — zero external dependencies,
drop-in ready.

Here's what I built:

🚀 1. Animated Onboarding Flow

3-step animated intro screen with:

Smooth fade animations via AnimationController
Animated page indicator dots
Skip button + customizable slides
Single .dart file

📱 2. Stories & Feed UI

Instagram-style social feed with:

Horizontal stories bar with animated gradient ring
Post cards with animated like button
Dark theme out of the box
Single .dart file

🛒 3. Product Card Kit

E-commerce grid with:

Scale animation on tap (feels premium)
Live cart counter in AppBar
Per-product accent colors
Single .dart file

💎 4. Pricing Plans

SaaS pricing screen with:

Monthly/Yearly animated toggle
Auto-calculated savings badge
"Most Popular" plan highlight
Single .dart file

💬 5. Chat Bubble UI

Real-time chat screen with:

Animated 3-dot typing indicator
Auto-scroll to latest message
Sent & received bubble styles
Single .dart file

Key Technical Decisions

Why single .dart files?

No pubspec.yaml changes needed. Copy the file,
import it, done. Developers hate dependency conflicts.

Why zero external packages?

Flutter's built-in widgets are powerful enough for
all of these. AnimationController, PageView,
ListView — everything is native.

Samsung Galaxy navigation bar bug

Learned this the hard way — always wrap your
bottom UI elements in SafeArea(top: false)
otherwise they get hidden behind the gesture
navigation bar on Android.

SafeArea(
  top: false,
  child: Container(
    // your input bar or bottom content
  ),
)

Also always set resizeToAvoidBottomInset: true
on your Scaffold when you have input fields.

Where to get them
