Web Cache Killer

Fixes Flutter web cache problems by automatically renaming JavaScript files with timestamps.

Why You Need This

When you deploy a Flutter web app, users often see the old version because browsers cache JavaScript files. This tool fixes that by renaming your JS files with timestamps so users always get the latest version.

Installation

dart pub global activate web_cache_killer

Quick Start

# Go to your Flutter project folder
cd my_flutter_project

# Build and create web.zip
web_cache_killer

# Build with custom name (creates beta.zip)
web_cache_killer --name beta

# Build and upload automatically
web_cache_killer --auto-upload

What It Does

Before:

flutter.js
main.dart.js

After:

flutter_20250801_143022_456.js
main_20250801_143022_456.dart.js

All HTML files are automatically updated to use the new names.
