Chatify Selection Addon

Optional message selection service for Chatify. Provides:

• Selection header (modal bar showing selected count and delete action)
• Drag-to-select listener over the messages list
• Per-message selection highlight and checkbox affordance

This addon plugs into Chatify via the addons API and can be enabled or disabled per app.

Installation

flutter pub add chatify_selection

Usage

Register the addon globally at init or per screen.

Global registration during init:

import 'package:chatify/chatify.dart';
import 'package:chatify_selection/chatify_selection.dart';

await Chatify.init(
  currentUser: currentUser,
  chatRepo: chatRepo,
  messageRepoFactory: (chat) => messageRepoFor(chat),
  uploaderFactory: (attachment) => uploaderFor(attachment),
  messageProviders: [
    // your message providers
  ],
  chatAddons: const [
    SelectionAddon(),
  ],
);

Or register on-demand before building chat screens:

ChatAddonsRegistry.instance.registerChatAddons(const [SelectionAddon()]);

What it adds

• Header contribution: SelectedMessagesHeader
• Messages wrapper: MessagesSelectionListener
• Per-message wrapper: MessageSelectionWidget

All three are wired through the SelectionAddon, so no direct imports of the widgets are needed in your app.

Notes

• The delete action uses your configured MessageRepo to delete selected messages.
• The addon is UI-only; style it via your app theme.

Features

• Long-press to select or toggle selection
• Drag to select/deselect a continuous range
• Modal header shows selected count and delete action
• Per-message selection indicator and highlight
• Addon-based integration; no UI changes required in your app

Getting started

1. Add the dependency (see Installation above)
2. Ensure Chatify.init is called in your app
3. Register SelectionAddon globally at init or before building chat screens
