textify 0.1.6

A cross-platform Flutter package that extracts text from clean digital images using standard fonts, run offline with no external dependencies.

Textify (OCR)

Textify is a Dart package that provides utilities for working with text representations in a specific character set. It is designed to handle text processing tasks for the English language and a limited set of characters.

It is 100% cross-platform, utilizing native Dart and Flutter code, and works offline without any package dependencies.

Features

• Extracts text from clean digital images
• Supports standard fonts like "Arial", "Courier", "Helvetica", "Times New Roman"
• Fully cross-platform
• Pure Dart and Flutter implementation
• Offline functionality
• No external package dependencies

Why Textify?

Textify addresses common limitations of existing OCR (Optical Character Recognition) solutions:

1. Lightweight: Most OCR libraries are heavy and often rely on external system dependencies or remote cloud services, complicating deployment and increasing costs.

2. Simplified Setup: Popular solutions like Tesseract require complex build configurations, including C/C++ compilation, which can be difficult to manage across platforms.

3. Web Compatibility: Many OCR solutions do not support Flutter web clients, limiting their cross-platform usability.

Textify overcomes these issues with a lightweight, pure Dart implementation that works seamlessly across all Flutter platforms, including web, without external dependencies.

Supported Characters

This package intentionally supports only the following characters:

• Uppercase letters: ABCDEFGHIJKLMNOPQRSTUVWXYZ
• Lowercase letters: abcdefghijklmnopqrstuvwxyz
• Digits: 0123456789
• Punctuation marks: /\(){}[]<>,;:.!@#$&*-+=?

Any text containing characters outside of this set may not be processed correctly or may result in errors.

Language Support

Textify is currently designed to work with the English language only. While it may handle some text in other languages that use the supported character set, its functionality is optimized and intended for English text processing.

Limitations and Requirements

While Textify offers significant advantages, it's essential to understand its limitations:

• Optimized for clean digital images with standard fonts.
• May struggle with complex layouts or handwritten text.
• For advanced OCR needs, consider other solutions.

Requirements for Optimal Performance

• Clean, computer-generated documents
• Minimal background noise (e.g., no watermarks)
• High contrast between text and background
• No handwritten or italic text
• Isolated characters (not touching other artifacts)

Getting Started

To use Textify in your Dart project, add it to your pubspec.yaml file:

dependencies:
  textify: ^latest_version

Then run:

flutter pub get

Usage

Here's a basic example of how to use Textify:

import 'dart:ui' as ui;
import 'package:textify/textify.dart';

void main() async {
  // Instentiate Textify
  final Textify textify = await Textify().init();

  // Use your image as source
  final ui.image imageSource = < standard images >

  final String text = await textify.getTextFromImage(image: imageSource);

  print(text);
}
