I have a bottom sheet where I have a List View of Text Fields, unfortunately I haven't found a way to scroll up the List View until the Text Field is visible.

As I am tapping on the 10th Text Field, the Keyboard hides the Text Field. Is there a way to scroll the item WITHIN the list view (not add insets to the whole list view) in such a way that it is not hidden?

Adding a Scaffold with "resizeToAvoidBottomInset" doesn't work in this case as it would scale the Bottom Sheet to the whole screen.

Thank you for your help!

Code sample:

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

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

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
        title: 'Flutter Demo',
        theme: ThemeData(
          primarySwatch: Colors.blue,
          brightness: Brightness.light,
        ),
        home: const TextFieldCovered()
        //  const MyHomePage(title: 'Flutter Demo Home Page'),
        );
  }
}

class TextFieldCovered extends StatelessWidget {
  const TextFieldCovered({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      resizeToAvoidBottomInset: false,
      body: Center(
        child: CupertinoButton(
          child: const Text('Bottom Sheet'),
          onPressed: () => modalBottomSheet(context),
        ),
      ),
    );
  }
}

void modalBottomSheet(BuildContext context) => showModalBottomSheet(
      context: context,
      builder: (context) => SizedBox(
        height: MediaQuery.of(context).size.height * 0.6,
        child: ListView.builder(
          itemBuilder: (context, index) => Container(
            color: index % 2 == 0 ? Colors.amber : Colors.greenAccent,
            child: Row(
              children: [
                Expanded(
                  flex: 3,
                  child: Text(
                    index.toString(),
                    textAlign: TextAlign.center,
                  ),
                ),
                const Expanded(
                  child: CupertinoTextField(),
                ),
              ],
            ),
          ),
        ),
      ),
    );

CodePudding user response：

1. Set showModalBottomSheet isScrollControlled property to true

2. Wrap ListView.builder on Padding with padding property set to

   EdgeInsets.only( bottom: MediaQuery.of(context).viewInsets.bottom)

3. Set Row mainAxisSize property to MainAxisSize.min

Now the modalBottomSheet should be look like this

void modalBottomSheet(BuildContext context) => showModalBottomSheet(
  context: context,
  isScrollControlled: true, //this
  builder: (context) => SizedBox(
    height: MediaQuery.of(context).size.height * 0.6,
    child: Padding( //this
      padding: EdgeInsets.only(
          bottom: MediaQuery.of(context).viewInsets.bottom), //this
      child: ListView.builder(
        itemBuilder: (context, index) => Container(
          color: index % 2 == 0 ? Colors.amber : Colors.greenAccent,
          child: Row(
            mainAxisSize: MainAxisSize.min, //this
            children: [
              Expanded(
                flex: 3,
                child: Text(
                  index.toString(),
                  textAlign: TextAlign.center,
                ),
              ),
              const Expanded(
                child: CupertinoTextField(),
              ),
            ],
          ),
        ),
      ),
    ),
  ),
);
