如何更改 Flutter TextButton 的高度? [英] How to change the Flutter TextButton height?

问题描述

这是输出:

1. 我尝试制作一个应用程序，但是当我使用 TextButton 时，我得到了两个按钮之间的空间
2. 我需要一个一个没有空格
3. 如果我使用 Expanded 小部件，ScrollChildView 不起作用
4. 我尝试了，但我无法清除这些东西.
5. 我尝试制作这种类型的TextButton.

1. I try to make an app but when I use the TextButton, I get the space between two Buttons
2. I need one by one without space
3. If I use the Expanded Widget, ScrollChildView doesn't work
4. I try but I can't clear this stuff.
5. I try to make this type of TextButton.

有人知道或对此有任何想法吗?

Anyone know or have any idea about this?

推荐答案

使用以下内容甚至添加您喜欢的尺寸

use the following to even add your preferred size as well

N/B:子大小的框是 Padding 小部件内的主要子小部件

N/B: child sized box is the main child widget inside Padding widget

Row(
                  mainAxisAlignment: MainAxisAlignment.center,
                  children: <Widget>[
                    Padding(
                      padding: const EdgeInsets.all(30.0),
                      child: SizedBox(
                        height: 60,
                        width: 200,
                        child: ElevatedButton.icon(
                          onPressed: () {
                            Navigator.push(
                                context,
                                MaterialPageRoute(
                                    builder: (context) => RegistrationMenu()));
                          },
                          style: ButtonStyle(
                            backgroundColor:
                                MaterialStateProperty.all(Colors.red.shade800),
                          ),
                          icon: Icon(Icons.person_add_alt_1_rounded, size: 18),
                          label: Text("Register Users"),
                        ),
                      ),
