Quick start

Requirements: Flutter 3.32+ · Dart 3.8+

flutter pub add flutter_icon_dialog

To use this major version explicitly:

dependencies:
  flutter_icon_dialog: ^2.0.0

import 'package:flutter_icon_dialog/flutter_icon_dialog.dart';

await showIconDialog<void>(
  context: context,
  title: 'Saved',
  content: 'Your changes have been saved.',
  iconTitle: true,
  iconType: AlertIconType.check,
);

Configuration

Option	Default	Purpose
context / title / content	required	Route context and message.
iconTitle	false	Replace the text heading with an animated icon.
iconType	AlertIconType.alert	Status icon.
actions	localized OK button	Custom action widget.
canGoBack	true	Allow system-back and barrier dismissal.
theme	IconDialogThemeData()	Optional icon, text, surface, and button overrides.
radius / width	8 / 300	Dialog shape and preferred width.
insetPadding	24	Horizontal route padding; vertical padding is 24.

Results and custom actions

final accepted = await showIconDialog<bool>(
  context: context,
  title: 'Continue?',
  content: 'Choose whether to continue.',
  actions: Builder(
    builder: (dialogContext) => TextButton(
      onPressed: () => Navigator.pop(dialogContext, true),
      child: const Text('Continue'),
    ),
  ),
);

Import package:flutter/material.dart for the Flutter widgets in this example. Use the dialog's own context when popping a route, especially with nested navigators.

canGoBack: false blocks system-back and barrier dismissal. Explicit Navigator.pop and the confirmation button can still close the dialog. Platform selection follows ThemeData.platform; web uses a Material route. The body uses Material styling on every platform.

CI validates Flutter 3.32.0 and the latest stable channel. When switching SDK versions locally, run flutter clean before testing to avoid reusing incompatible compiled shader assets.

Upgrading from 1.x
