在你的 android 手机上打开 Flutter 主题工具应用程序 。按照指南为你的应用程序准备一个很棒的 Dart 主题。

将生成的 Dart 主题代码复制到剪贴板中。

要在您的计算机上获取主题，请在 IDE 中，(例如 Visual Studio Code)。将其粘贴到您手机上的 slack 聊天中，以便您可以从计算机上的 slack 获取代码。在移动设备 slack 上，输入 ```。将出现一个框。将剪贴板内容粘贴到该框中。

可选：按照相同的步骤为黑暗模式生成另一个 Dart 主题。

打开您现有的 flutter 项目。使用以下内容创建 generated_theme.dart 文件。

import 'package:flutter/material.dart';ThemeData get mylightTheme {// TODO: Copy Generated Light Theme Here.
return theme;
}ThemeData get myDarkTheme {// TODO: Copy Generated Dark Theme Here.
return theme;
}

用生成的代码替换 TODO 注释。

ThemeData get mylightTheme {
// Flutter Theming Tool 1.0.0+10, developed by Tamata Soft
// Initialize ThemeData.
  var theme = ThemeData(
    primarySwatch: Colors.blue,
    brightness: Brightness.light,
  );// Main Setting.
  theme = theme.copyWith(
    colorScheme: theme.colorScheme.copyWith(
      onPrimary: const Color(0xffffffff),
      secondary: Colors.deepOrange,
    ),
  );// ElevatedButton Setting.
  theme = theme.copyWith(
    elevatedButtonTheme: ElevatedButtonThemeData(
      style: ButtonStyle(
        shape: MaterialStateProperty.all(
          const RoundedRectangleBorder(
            borderRadius: BorderRadius.only(
              topLeft: Radius.circular(16.0),
              topRight: Radius.circular(16.0),
            ),
          ),
        ),
      ),
    ),
  );// OutlinedButton Setting.
  theme = theme.copyWith(
    outlinedButtonTheme: OutlinedButtonThemeData(
      style: ButtonStyle(
        shape: MaterialStateProperty.all(
          const RoundedRectangleBorder(
            borderRadius: BorderRadius.only(
              topLeft: Radius.circular(16.0),
              topRight: Radius.circular(16.0),
            ),
          ),
        ),
      ),
    ),
  );// Chip Setting.
  theme = theme.copyWith(
    chipTheme: theme.chipTheme.copyWith(
      shape: const RoundedRectangleBorder(
        borderRadius: BorderRadius.only(
          topLeft: Radius.circular(16.0),
          bottomRight: Radius.circular(16.0),
        ),
      ),
      labelStyle: (theme.chipTheme.labelStyle).copyWith(
        color: Colors.deepOrange,
        shadows: [
          const Shadow(
            blurRadius: 2.0,
            color: Colors.grey,
          )
        ],
      ),
      secondaryLabelStyle: (theme.chipTheme.labelStyle).copyWith(
        shadows: [
          const Shadow(
            blurRadius: 2.0,
          )
        ],
      ),
    ),
  );
  return theme;
}

打开 main.dart 文件。在 MaterialApp 小部件中添加 theme 属性。

MaterialApp(
 title: 'Flutter Demo',
 theme: mylightTheme,
 ----
 ----
)
