Chip Email

A sophisticated Flutter package designed for high-performance, professional email input. Chip Email provides an interactive, keyboard-aware interface for managing multiple email addresses with technical precision.

Background

The Problem

Managing multiple email inputs in mobile applications often leads to significant user experience challenges:

1. Input Clutter: Long lists of email addresses become visually overwhelming and difficult to edit.
2. Lack of Context: Standard text fields do not distinguish between individual email entities.
3. Inefficient Extraction: Manually separating emails from bulk text (e.g., CSV) is tedious for users.
4. Non-Native Feel: Many chip implementations lack the professional keyboard behaviors expected in modern operating systems.

The Solution

Chip Email addresses these challenges by providing a "True Inline" input architecture that treats each email as a first-class interactive object. It integrates chips and the text cursor into a single dynamic flow, supporting standard professional behaviors such as backspace navigation and intelligent extraction.

Features

• True Inline Architecture: Chips and text flow together natively.
• Professional Interaction: Industry-standard keyboard awareness, including backspace-to-select logic.
• Intelligent Extraction: Automated parsing logic for bulk ingestion of email lists.
• Adaptive Styling: Inherits application themes and design systems without opinionated overrides.
• Form Ready: Full integration with Flutter's Form and FormField state management.

Implementation Steps

Step 1: Install Dependencies

Add the package to your pubspec.yaml file:

flutter pub add chip_emails

Step 2: Initialize the Widget

Incorporate the EmailChipInput widget into your view. It adapts to any standard InputDecoration.

EmailChipInput(
  decoration: InputDecoration(
    hintText: "Enter recipients...",
    border: OutlineInputBorder(
      borderRadius: BorderRadius.circular(12),
    ),
  ),
  onChanged: (emails) {
    // Process the list of validated emails
  },
)

Step 3: Advanced State Management (Optional)

Utilize the ChipEmailController for programmatic control over the email list.

final controller = ChipEmailController(
  initialEmails: ['admin@company.com'],
);

EmailChipInput(controller: controller);
