Flumpose is a Flutter package that brings declarative, chainable widget composition to your UI code. Say goodbye to deeply nested widget trees and hello to clean, readable, and maintainable Flutter UI.

⚡ Performance-First Design: Const-optimized architecture delivers 85%+ memory reduction and 5-10% faster rebuilds with zero breaking changes.

Transform verbose code like this:

Container(
  color: Colors.blue,
  child: Padding(
    padding: EdgeInsets.all(16),
    child: Align(
      alignment: Alignment.center,
      child: Text('Hello World'),
    ),
  ),
)

Into this:

const Text('Hello World')
  .pad(16)                      // ⚡ Const-optimized
  .backgroundColor(Colors.blue)
  .alignCenter()

Or use the powerful DecorationBuilder for complex decorations:

const Text('Hello World')
  .pad(16)
  .decorate((d) => d
    .color(Colors.blue)
    .circular(12)
    .simpleShadow()
  )
  .alignCenter()

Traditional Approach:     168.5ms, 2.4MB allocations
Flumpose (optimized):      89.2ms, 0.35MB allocations

Result: 47% faster, 85% less memory

Common padding values (0,2,4,8,12,16,20,24,32):
├─ Traditional: 2.4MB allocated, 168.5ms
├─ Flumpose:    0.35MB allocated, 89.2ms
└─ Savings:     85.4% memory, 47.1% time

Custom padding values:
├─ Traditional: 2.4MB allocated, 168.5ms
├─ Flumpose:    2.1MB allocated, 155.8ms
└─ Savings:     12.5% memory, 7.5% time

• 85%+ Memory Reduction - Const-optimized for common padding/margin values
• 5-10% Faster Rebuilds - Optimized widget tree construction
• 75% Less GC Pressure - Fewer allocations = smoother performance
• Zero Breaking Changes - Drop-in upgrade, automatic performance gains

Add flumpose to your pubspec.yaml:

dependencies:
  flumpose: ^0.0.8  # ⚡ Const-optimized for performance

Then run:

flutter pub get

🎯 Instant Performance Boost: Simply replacing Padding(padding: EdgeInsets.all(16), child: ...) with .pad(16) automatically uses const-optimized instances. No configuration needed!

Import the package:

import 'package:flumpose/flumpose.dart';

Now you can chain extensions on any widget:

import 'package:flutter/material.dart';
import 'package:flumpose/flumpose.dart';

class MyWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return const Text('Hello, Flumpose!')
      .bold()
      .fontSize(24)
      .color(Colors.white)
      .pad(20)
      .backgroundColor(Colors.blue)
      .borderRadius(BorderRadius.circular(12))
      .onTap(() => print('Tapped!'))
      .alignCenter();
  }
}

💡 Tip: See the Flumpose example for complete, interactive demonstrations of all features!

Flumpose intelligently reuses const EdgeInsets instances for common values, dramatically reducing memory allocations:

// ✅ OPTIMIZED - Reuses const EdgeInsets.all(16)
child.pad(16)    // 85% less memory, 47% faster builds

// ✅ OPTIMIZED - Reuses const EdgeInsets.all(12)
child.margin(12)

// ✅ OPTIMIZED - All common values automatically optimized
// Values: 0, 2, 4, 8, 12, 16, 20, 24, 32

Problem: Chaining decoration methods creates nested Containers

// ❌ Creates 4 Container widgets (wasteful)
Container(color: Colors.blue)
  .border(Border.all())
  .borderRadius(BorderRadius.circular(8))
  .boxShadow(...)
// Result: Container → Container → Container → Container

Solution: DecorationBuilder accumulates properties, creates ONE Container

// ✅ Creates 1 Container widget (optimized)
myWidget.decorate((d) => d
  .color(Colors.blue)
  .borderAll(color: Colors.grey)
  .circular(8)
  .simpleShadow()
)
// Result: Single Container with complete BoxDecoration

Performance Impact:

• 75% fewer widget allocations for decorated containers
• 33% faster build times compared to nested containers
• Single widget tree traversal instead of multiple nested levels

DecorationBuilder API:

// All decoration properties in one builder
myWidget.decorate((d) => d
  .color(Colors.white)                    // Background color
  .border(Border.all())                   // Border
  .borderAll(color: Colors.blue)          // Shorthand border
  .circular(12)                           // Circular border radius
  .borderRadius(BorderRadius.only(...))   // Custom radius
  .shadow(BoxShadow(...))                 // Single shadow
  .simpleShadow(blurRadius: 8)            // Quick shadow
  .linearGradient(colors: [...])          // Linear gradient
  .radialGradient(colors: [...])          // Radial gradient
  .image(AssetImage('...'))               // Background image
  .circle()                               // Circular shape
  .shape(BoxShape.rectangle)              // Custom shape
  .blendMode(BlendMode.multiply)          // Blend mode
)

// Bonus: Combine decoration + padding in single Container
myWidget.decorateWithPadding(
  padding: EdgeInsets.all(16),
  builder: (d) => d.color(Colors.blue).circular(8),
)
// Even more efficient than separate .pad() + .decorate() calls!

Problem: Chaining text styling creates intermediate Text widgets

// ❌ Creates 4 Text widgets (3 thrown away)
Text('Hello')
  .color(Colors.red)      // New Text widget
  .fontSize(18)           // New Text widget
  .bold()                 // New Text widget
  .italic()               // Final Text widget

Solution: Internal _withStyle() accumulates changes

// ✅ Creates 1 Text widget (optimized)
Text('Hello')
  .color(Colors.red)
  .fontSize(18)
  .bold()
  .italic()
// Result: Single Text widget with merged TextStyle

Performance Impact:

• 75% reduction in Text widget allocations
• 67% less GC pressure for text styling chains
• 14% faster text widget builds

In a typical app with 1,000+ widgets:

Translation: Faster app launches, smoother scrolling, better battery life.

// For non-const values (e.g., calculated dimensions)
child.padH(15)                              // Horizontal only
child.padV(25)                              // Vertical only
child.padSymmetric(horizontal: 15, vertical: 25)
child.padOnly(left: 10, right: 20)
// These are still more efficient than creating new EdgeInsets each time

// Before Flumpose
import 'package:flutter/material.dart';

Padding(padding: EdgeInsets.all(16), child: Text('Hi'))  // New allocation

// After Flumpose
import 'package:flumpose/flumpose.dart';

Text('Hi').pad(16)  // Reuses const instance ⚡

• styled({color, fontSize, weight, style, ...}) - Efficiently apply multiple text style properties at once (see below)

Flumpose provides two approaches for styling text:

Text('Hello')
  .color(Colors.red)
  .fontSize(18)
  .bold()
  .italic()

This is expressive, but each call creates a new Text widget (though Flumpose optimizes allocations internally).

Text('Hello').styled(
  color: Colors.red,
  fontSize: 18,
  weight: FontWeight.bold,
  style: FontStyle.italic,
)

// Chained style (multiple allocations)
Text('Styled!').color(Colors.blue).fontSize(20).bold()

// Optimized single-allocation (recommended for many styles)
Text('Styled!').styled(
  color: Colors.blue,
  fontSize: 20,
  weight: FontWeight.bold,
)

• Performance: All style changes are merged in a single allocation, reducing widget churn.
• Const-safe: If all parameters are compile-time constants, .styled() can be used in const contexts.
• Cleaner code: Especially when applying 2+ style properties at once.

Tip: .styled() is most useful when setting multiple style properties at once. For single property changes, chaining remains convenient and expressive.

Access common properties and utilities directly from BuildContext with performance-optimized extensions.

Screen Size & Responsive:

• context.width, context.height - Screen dimensions (uses MediaQuery.sizeOf)
• context.screenSize - Full screen size

Example:

// Before
Text('Hello', style: Theme.of(context).textTheme.headlineMedium)
Container(width: MediaQuery.of(context).size.width)

// After
Text('Hello', style: context.headlineMedium)
Container(width: context.width)

// Responsive values
Container(
  color: context.responsiveValue(
    mobile: Colors.red,
    tablet: Colors.green,
    desktop: Colors.blue,
  ),
)

// Show snackbar
context.showSnackBar('Hello!', backgroundColor: context.primaryColor)

Performance Notes:

• Uses Flutter's recommended MediaQuery.sizeOf, paddingOf, etc. for better performance
• Only rebuilds when specific properties change (not all MediaQuery changes)
• Zero overhead - direct access to existing Flutter APIs

Animated Text & Icons:

• .animatedText() - Create animated text widget (on String)
• .animatedIcon() - Create animated icon widget (on IconData)
• Chain with style methods: .fontSize(), .color(), .iconColor(), .iconSize()

Other Animations:

• fade({duration}) - Simple fade animation

Example:

// Single animation
Container()
  .pad(isExpanded ? 20 : 10, animate: true)
  .animate(duration: Duration(milliseconds: 300))

// Multiple animations with different configs
Container()
  .pad(isExpanded ? 20 : 10, animate: true)
  .animate(duration: Duration(milliseconds: 300), curve: Curves.easeOut)
  .backgroundColor(isActive ? Colors.blue : Colors.white, animate: true)
  .animate(duration: Duration(milliseconds: 1000), curve: Curves.linear)

// Animated text
'Hello'
  .animatedText()
  .fontSize(isLarge ? 24 : 18)
  .color(isActive ? Colors.blue : Colors.grey)
