Android 如何在一个屏幕上安装所有这些颤振小部件?

Android 如何在一个屏幕上安装所有这些颤振小部件?,android,flutter,dart,Android,Flutter,Dart,我正在构建这个颤振应用程序。我的问题是我不能在一个屏幕上安装所有的小部件。所有的字体大小和图标看起来都不一样,尽管它们本来是一样的。在ReusableCard中,当容器高度和宽度属性分别设置为200和250时,整个应用程序会调整大小,但它们并不统一,如图所示。有人有什么建议吗 import 'results_page.dart'; import 'package:flutter/material.dart'; import 'package:font_awesome_flutter/font_a
