I get this error while trying to put TextField inside my app:

'package:flutter/src/widgets/binding.dart': Failed assertion: line 858 pos 12: '!debugBuildingDirtyElements': is not true.

Here is a screenshot of the error. I even tried to use TextFormField but I got the same error:

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

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        body: Row(
          children: [
            Column(
              children: const [
                TextField(),
              ],
            )
          ],
        ),
      ),
    );
  }
}

CodePudding user response：

Wrap your Column with Expanded to get available space inside Row.

body: Row(
  children: [
    Expanded(
      child: Column(
        children: [
          TextField(),
        ],
      ),
    )
  ],
)

You can check unbounded-height/width video

CodePudding user response：

TextField has unbounded width, so if you want to use it inside row you should give it specific size by wrapping column with Expanded.like this:

Row(
            children: [
              Expanded(
                child: Column(
                  children: const [
                    TextField(),
                  ],
                ),
              )
            ],
          )
