mutable_icon 1.1.1

Animate from any icon to any icon programally but without ripple and events.

Animate any two icons

mutable_icon is a simplified version of animate_icons. Watch the demo for more details. It is specifically designed to be included within other widgets that already have their own behavior and only need to animate an icon.

Demo:

How to use:

All plugin in your pubspec.yaml

mutable_icon:

Make the import:

import 'package:mutable_icon/mutable_icon.dart';

Use the following widget:

    MutableIcon(
        startIcon: Icons.add_circle,
        endIcon: Icons.add_circle_outline,
        controller: controller,
        size: 32.0,
        duration: Duration(milliseconds: 400),
        startIconColor: Colors.deepPurple,
        endIconColor: Colors.deepOrange,
        clockwise: false,
        initFrom: InitFrom.end,
    ),

Use MutableIconController

Define MutableIconController to animate b/w start and end icons.

Define MutableIconController

MutableIconController controller;

Initialize controller

controller = MutableIconController();

Pass controller to widget

MutableIcon(
    startIcon: Icons.add,
    endIcon: Icons.close,
    controller: controller, 
),

Use controller functions

if (controller.isStart()) {
    controller.animateToEnd();
} else if (controller.isEnd()) {
    controller.animateToStart();
}

Full example

import 'package:flutter/material.dart';

import 'package:mutable_icon/mutable_icon.dart';

void main() => runApp(const Example());

class Example extends StatefulWidget {
  const Example({Key? key}) : super(key: key);

  @override
  State<Example> createState() => _ExampleState();
}

class _ExampleState extends State<Example> {
  bool _submenu = false;
  late final MutableIconController _controller;

  @override
  void initState() {
    _controller = MutableIconController();
    super.initState();
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      title: 'MutableIcon Example',
      home: Scaffold(
        body: ListView(
          children: [
            ListTile(
              leading: const Icon(
                Icons.wallet,
                color: Colors.black
              ),
              title: const Text('Wallet'),
              trailing: MutableIcon(
                duration: const Duration(milliseconds: 300),
                startIcon: Icons.expand_more,
                endIcon: Icons.expand_less,
                startIconColor: Colors.black,
                endIconColor: Colors.black,
                controller: _controller,
                initFrom: _submenu ? InitFrom.end : InitFrom.start
              ),
              onTap: () {
                setState(() {
                  _submenu = !_submenu;
                  if (_submenu) {
                    _controller.animateToEnd();
                  } else {
                    _controller.animateToStart();
                  }
                });
              },
            ),
            if (_submenu) ListTile(
              contentPadding: const EdgeInsets.only(left: 32),
              leading: const Icon(
                Icons.account_balance,
                color: Colors.black
              ),
              title: const Text('Balance'),
              onTap: () {},
            ),
          ],
        )
