censor 1.0.2

A Flutter widget that creates a TV static/noise effect for censoring content.

Censor

A Flutter widget that overlays animated black and white particles on top of any child widget when censored, creating a TV static/noise effect for hiding sensitive content.

Demo example

Features

• 🎭 Overlay animated particles pattern on any widget
• ⚡ Smooth, efficient animation using CustomPainter
• 🎨 Customizable particles size, spacing, and animation speed
• 🔧 Works with any child widget (Text, Image, Container, etc.)
• 📦 Zero dependencies (uses only Flutter SDK)

Getting started

Add this to your package's pubspec.yaml file:

dependencies:
  censor:
    path: ../censor  # Or your package path

Then run:

flutter pub get

Usage

Basic Example

import 'package:censor/censor.dart';

Censor(
  censored: true,
  child: Text(
    'Secret Information',
    style: TextStyle(fontSize: 24),
  ),
)

Advanced Example with Custom Settings

Censor(
  censored: shouldCensor,
  particlesSize: 4.0,          // Size of each particles
  particlesSpacing: 5.0,       // Space between particless
  animationSpeed: 2.0,         // Animation speed multiplier
  child: Container(
    width: 200,
    height: 150,
    child: Image.network('https://example.com/image.jpg'),
  ),
)

Interactive Example

class MyWidget extends StatefulWidget {
  @override
  State<MyWidget> createState() => _MyWidgetState();
}

class _MyWidgetState extends State<MyWidget> {
  bool _isCensored = true;

  @override
  Widget build(BuildContext context) {
    return Column(
      children: [
        Censor(
          censored: _isCensored,
          child: Text('Confidential Data'),
        ),
        ElevatedButton(
          onPressed: () => setState(() => _isCensored = !_isCensored),
          child: Text(_isCensored ? 'Reveal' : 'Hide'),
        ),
      ],
    );
  }
}

Parameters

Parameter	Type	Default	Description
child	Widget	required	The widget to be censored
censored	bool	required	Whether to show the censored overlay
particlesSize	double	3.0	The size of each particle in pixels
particlesSpacing	double	4.0	The spacing between particles in pixels
animationSpeed	double	1.0	Animation speed multiplier (higher = faster)

How It Works

The Censor widget uses a Stack to overlay a CustomPaint widget on top of the child when censored is true. The CustomPaint uses an AnimationController to continuously redraw random black and white particles, creating the animated static effect.
