Live Demo: MP4 to MP3 Converter | Flutter Mobile App Live Demo

MP4 to MP3 Converter | Flutter Mobile App is a complete, ready-to-publish Flutter source code that empowers users to convert any video from their phone into a high-quality MP3 audio file. This app operates entirely offline, requiring no internet connection, subscriptions, or server dependencies.

Product Overview

This app leverages the power of FFmpeg, a renowned multimedia framework, to deliver seamless video-to-audio conversion. Designed with Material 3 guidelines, it boasts a modern and intuitive user interface. The app's architecture is built upon the clean and efficient Riverpod state management system, ensuring smooth performance and maintainability.

Core Conversion Features

• Versatile Conversion: Convert any MP4 video (or any video format supported by FFmpeg) into an MP3 audio file.
• Customizable Bitrates: Choose from a range of bitrates (96 kbps, 128 kbps, 192 kbps, 256 kbps, 320 kbps) to optimize audio quality and file size.
• Real-Time Progress Tracking: Monitor the conversion process with a dynamic progress bar that displays the percentage completion in real-time.
• Cancel Conversion: Stop the conversion process at any point during the conversion if needed.
• Audio Stream Detection: The app intelligently detects if the selected video contains an audio stream. If not, it will alert the user accordingly.

Smart File Management

• Custom Save Location: Users can choose a custom folder on their device to save the converted MP3 files.
• Fallback to Downloads: If no custom folder is selected, the converted files will be saved to the device's Downloads folder.
• Duplicate File Handling: The app automatically handles duplicate file names by appending numbers to the file names (e.g., "song (1).mp3", "song (2).mp3").
• Persistent Folder Permissions: The app retains permissions to the selected save folder across app restarts.

Conversion History

• File History: Every conversion performed is automatically recorded in a history list.
• File Details: The history list displays the file name, duration, bitrate, file size, and conversion date for each converted file.
• Direct Playback: Users can play converted MP3 files directly within the app using the built-in audio player.
• Sharing and Opening: Users can share or open converted files with other external apps, such as music players or cloud storage services.
• History Management: Users can delete individual history records or clear the entire history list with a single tap.

Settings & Customization

• Reset Save Location: Users can reset the save location to the default Downloads folder.
• Dark/Light Mode Toggle: Users can switch between Dark and Light modes manually from the AppBar.

Design & Architecture

• Material 3 Design: The app adheres to Material 3 design principles, incorporating adaptive Dark and Light themes for a modern and visually appealing user experience.
• Riverpod State Management: The app utilizes Flutter Riverpod 2.6 for efficient state management, ensuring smooth updates and responsiveness.
• Clean Code Structure: The codebase is organized into distinct folders for screens, services, widgets, providers, and models, promoting readability and maintainability.
• Local History Persistence: The app uses SharedPreferences to persist history data locally, ensuring data retention even when the app is closed.
