Flutter doesn't want to render Expanded widget inside Row

Time：09-02

My intention

I am learning Flutter through a personal project and I want my "Edit profile" OutlinedButton to be as far as possible from the two Text widgets on the left.

This is an edited image to illustrate my goal.

goal

In the following image I use a Container to display the informations

My Problem

But when I change the Container (which contains a Row in which there are the two Text Widgets) to an Expanded widget, my page is blank and an error mentions

Unexpected null value

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

  @override
  Widget build(BuildContext context) {
    return Row(
      children: [
        Expanded(
            child: Row(
                mainAxisAlignment: MainAxisAlignment.start,
                children: [
                  Text(context.watch<WobbleNotifier>().account?.username ?? "user"),
                  Text(context.watch<WobbleNotifier>().account?.email ?? "email"),
                ]
            )
        ),
        OutlinedButton(
            onPressed: null,
            child: Text(AppLocalizations.of(context)!.editProfile)
        )
      ],
    );
  }
}

Thank you for any input on how to solve this !

Context

The AccountInformation widget is contained in this panel:

class AccountPanel extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Container(
      padding: const EdgeInsets.all(20),
      decoration: BoxDecoration(
        color: Colors.white,
        boxShadow: [
          BoxShadow(
            color: Colors.grey.withOpacity(0.5),
            spreadRadius: 3,
            blurRadius: 6,
            offset: const Offset(0, 3),
          ),
        ],
      ),
      child: Row(
        children: [
          const Icon(Icons.person),
          Column(
            children: [
              const AccountInformation(),
              Row(
                children: [
                  Column(
                    children: [
                      const Text('0'),
                      Text(AppLocalizations.of(context)!.workouts),
                    ],
                  ),
                  Column(
                    children: [
                      const Text('0'),
                      Text(AppLocalizations.of(context)!.followers),
                    ],
                  ),
                  Column(
                    children: [
                      const Text('0'),
                      Text(AppLocalizations.of(context)!.following_plural),
                    ],
                  ),
                ]
              )
            ],
          )
        ],
      ),
    );
  }

  const AccountPanel({Key? key}) : super(key: key);
}

And the panel is in a ListView

@override
  Widget build(BuildContext context) {
    return ListView(
      children: const [
        AccountPanel()
      ],
    );
  }

CodePudding user response：

You have to encapsulate a row in a row and put a space between to the first row. The first row contains the second row and the input.

-> Row
-> Space Between (important)
--> Row
----> Text
----> Text
--> Input

Try this :

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

  @override
  Widget build(BuildContext context) {
    return Row(
      mainAxisAlignment: MainAxisAlignment.spaceBetween,
      children: [
        Row(children: [
          Text(context.watch<WobbleNotifier>().account?.username ?? "user"),
          // add a space between the username and the icon if you want
          Text(context.watch<WobbleNotifier>().account?.email ?? "email"),
        ]),
        OutlinedButton(
            onPressed: null,
            child: Text(AppLocalizations.of(context)!.editProfile))
      ],
    );
  }
}

Play with padding.

enter image description here

class AccountPanel extends StatelessWidget {
  const AccountPanel({Key? key}) : super(key: key);
  @override
  Widget build(BuildContext context) {
    return Container(
      padding: const EdgeInsets.all(20),
      child: Row(
        children: [
          const Icon(Icons.person),
          Expanded(
            child: Column(
              mainAxisSize: MainAxisSize.min,
              children: [
                AccountInformation(),
                Row(
                  children: [
                    Column(
                      children: [
                        const Text('0'),
                        Text("workouts"),
                      ],
                    ),
                    Column(
                      children: [
                        const Text('0'),

            ),
          ),
        ],
      ),
    );
  }

            children: [
              Text("user"),
              Text("email"),
            ],
          ),
        ),
        Padding(
          padding: const EdgeInsets.only(left: 18.0),

CodePudding user response：

I didn't want to use paddings as they use fixed values and it would have looked different on other screens but thanks to your answer @yeasin-sheikh I found a solution by wrapping the Column containing the AccountInformation Widget in an Expanded widget.

So I achieved my goal only using Expanded.

Now I need to understand why it works.

enter image description here

import 'package:app/widgets/account/account.information.dart';
import 'package:flutter/material.dart';
import 'package:flutter_gen/gen_l10n/app_localizations.dart';

class AccountPanel extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Container(
      padding: const EdgeInsets.all(20),
      decoration: BoxDecoration(
        color: Colors.white,
        boxShadow: [
          BoxShadow(
            color: Colors.grey.withOpacity(0.5),
            spreadRadius: 3,
            blurRadius: 6,
            offset: const Offset(0, 3),
          ),
        ],
      ),
      child: Row(
        children: [
          const Icon(Icons.person),
          // Here, I wrapped everything in the Expanded widget
          Expanded(child: Column(
            children: [
              const AccountInformation(),
              Row(
                  children: [
                    Column(
                      children: [
                        const Text('0'),
                        Text(AppLocalizations.of(context)!.workouts),
                      ],
                    ),
                    Column(
                      children: [
                        const Text('0'),
                        Text(AppLocalizations.of(context)!.followers),
                      ],
                    ),
                    Column(
                      children: [
                        const Text('0'),
                        Text(AppLocalizations.of(context)!.following_plural),
                      ],
                    ),
                  ]
              )
            ],
          ))
        ],
      ),
    );
  }

  const AccountPanel({Key? key}) : super(key: key);
}
