Multiline Textfield List don't add newline when pressing Enter

I have a problem with multiline Textfield list. When i press enter, it dont makes new line, only if typing more characters. How to get newline with pressing enter? The textfield by itself works well, but not in a list.

import 'package:flutter/material.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      // Application name
      title: 'Flutter Hello World',
      // Application theme data, you can set the colors for the application as
      // you want
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      // A widget which will be started on application startup
      home: MyHomePage(),
    );
  }
}

class MyHomePage extends StatelessWidget {
  final List<MultiLineTextField> items;
  MyHomePage() : items = List<MultiLineTextField>.generate(200, (i) => MultiLineTextField('Text1 $i'));
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        // The title text which will be shown on the action bar
        title: Text('title'),
      ),
      body: ListView.builder(
        // Let the ListView know how many items it needs to build.
        itemCount: 100,
        itemBuilder: (context, index) {
          final item = items[index];
          return ListTile(
            title: item.build(context),
          );
        },
      ),
    );
  }
}

class MultiLineTextField extends StatelessWidget {
  const MultiLineTextField(String this.hint);
  final String hint;
  @override
  Widget build(BuildContext context) {
    return const TextField(
      keyboardType: TextInputType.multiline,
      maxLines: null,
      textInputAction: TextInputAction.newline,
      decoration: InputDecoration(
        hintText: 'text',
        fillColor: Colors.red,
      ),
    );
  }
}

try give a value in maxLines instead of null.

Seems, its working on gphone emulator , but not on samsung device.
