3.x.x: Wrapping in InputDecorator breaks layout #154

Open divan opened 2 months ago

divan commented 2 months ago

After upgrading to 3.x.x there is no way to achieve consistent field look&feel throught default Flutter's InputDecoration. Many people have code that provides InputDecoration to their fields' widgets. 3.x.x update removed this possibility.

Related issues: https://github.com/oi-narendra/multiselect-dropdown/issues/144 https://github.com/oi-narendra/multiselect-dropdown/issues/150

One of the solutions in these cases is to use InputDecorator widget and wrap field into it(removing all decoration in the child).

However, wrapping into InputDecorator somehow throws hard to decipher error.

Code to reproduce:

import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';
import 'package:go_router/go_router.dart';
import 'package:multi_dropdown/multi_dropdown.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp.router(
      title: 'Multiselect dropdown demo',
      debugShowCheckedModeBanner: false,
      themeMode: ThemeMode.dark,
      theme: ThemeData(
        primarySwatch: Colors.green,
      ),
      routerConfig: GoRouter(routes: [
        GoRoute(
          path: '/',
          builder: (context, state) {
            return const MyHomePage();
          },
        ),
      ]),
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({super.key});

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class User {
  final String name;
  final int id;

  User({required this.name, required this.id});

  @override
  String toString() {
    return 'User(name: $name, id: $id)';
  }
}

class _MyHomePageState extends State<MyHomePage> {
  final _formKey = GlobalKey<FormState>();

  final controller = MultiSelectController<User>();

  @override
  Widget build(BuildContext context) {
    var items = [
      DropdownItem(label: 'Nepal', value: User(name: 'Nepal', id: 1)),
      DropdownItem(label: 'Australia', value: User(name: 'Australia', id: 6)),
      DropdownItem(label: 'India', value: User(name: 'India', id: 2)),
      DropdownItem(label: 'China', value: User(name: 'China', id: 3)),
      DropdownItem(label: 'USA', value: User(name: 'USA', id: 4)),
      DropdownItem(label: 'UK', value: User(name: 'UK', id: 5)),
      DropdownItem(label: 'Germany', value: User(name: 'Germany', id: 7)),
