flutter scrollable selectable text

I have a reading application, where I show massive bodies of text. For performance issues I'm splitting up this text in chunks and displaying in a ListView.builder() widget

The problem arises when I want to make the text selectable with SelectableText widget. Because text is split between list items, I can't select between them. Basically text is only selectable in a list item.

Solution would be to display text without performance issues along with the ability to select between chunks or whole text

You need to wrap your SingleChildScrollView in an Expanded widget and you will get what you are looking for.

import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
   @override
   Widget build(BuildContext context) {
    return new MaterialApp(
  title: 'Flutter Demo',
  theme: new ThemeData(
    primarySwatch: Colors.blue,
    ),
      home: new MyHomePage(),
    );
   }
  }

 class MyHomePage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    var size = MediaQuery
    .of(context)
    .size;
  final double itemHeight = (size.height - kToolbarHeight - 24) / 2;
  final double itemWidth = size.width;

return new Container(
  child: new Column(
    crossAxisAlignment: CrossAxisAlignment.start,
    children: <Widget>[
      new Padding(
        padding: const EdgeInsets.fromLTRB(0.0, 24.0, 0.0, 0.0),
        child: new Image.asset(
          'assets/rp1.jpg',
          height: 200.0,
          width: itemWidth,
        ),
      ),
      new Padding(
        padding: const EdgeInsets.all(12.0),
        child: new Text(
          "Some Heading Text",
          style: new TextStyle(
              fontSize: 28.0,
              color: Colors.white,
              fontWeight: FontWeight.w600),
        ),
      ),
      new Expanded(
        flex: 1,
        child: new SingleChildScrollView(
          scrollDirection: Axis.vertical,//.horizontal
          child: new Text(
            "1 Description that is too long in text format(Here Data is coming from API) jdlksaf j klkjjflkdsjfkddfdfsdfds " + 
            "2 Description that is too long in text format(Here Data is coming from API) d fsdfdsfsdfd dfdsfdsf sdfdsfsd d " + 
            "3 Description that is too long in text format(Here Data is coming from API)  adfsfdsfdfsdfdsf   dsf dfd fds fs" +

            "8 Description that is too long in text format(Here Data is coming from API)" +

            "10 Description that is too long in text format(Here Data is coming from API)",     
            style: new TextStyle(
              fontSize: 16.0, color: Colors.white,
            ),
          ),
        ),
      ),
    ],
    ),
  );
 }
 }
