我正在尝试更改 OutlineInputBorder 的边框颜色,但尝试了很多方法而且失败了 .

我通过 buildDarkTheme() 函数创建了整个主题配置,但我无法将边框颜色更改为黄色

下面是图片和代码:

enter image description here

import 'package:flutter/material.dart';

void main() => runApp(new MyApp());

const kBlackHalf = const Color(0xFF212121);
const kBlackLight = const Color(0xFF484848);
const kBlack = const Color(0xFF000000);
const kYellow = const Color(0xFFffd600);
const kYellowLight = const Color(0xFFffff52);
const kYellowDark = const Color(0xFFc7a500);
const kWhite = Colors.white;

ThemeData buildDarkTheme() {
  final ThemeData base = ThemeData();
  return base.copyWith(
    primaryColor: kBlack,
    accentColor: kYellow,
    scaffoldBackgroundColor: kBlackHalf,
    primaryTextTheme: buildTextTheme(base.primaryTextTheme, kWhite),
    primaryIconTheme: base.iconTheme.copyWith(color: kWhite),
    buttonColor: kYellow,
    textTheme: buildTextTheme(base.textTheme, kWhite),    
    inputDecorationTheme: InputDecorationTheme(
      border: OutlineInputBorder(
        borderSide: BorderSide(color: kYellow)
      ),
      labelStyle: TextStyle(
        color: kYellow,
        fontSize: 24.0
      ),
    ),
  );
}

TextTheme buildTextTheme(TextTheme base, Color color) {
  return base.copyWith(
    body1: base.headline.copyWith(color: color, fontSize: 16.0),
    caption: base.headline.copyWith(color: color),
    display1: base.headline.copyWith(color: color),
    button: base.headline.copyWith(color: color),
    headline: base.headline.copyWith(color: color),
    title: base.title.copyWith(color: color),
  );
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return new MaterialApp(
      theme: buildDarkTheme(),
      home: new HomePage(),
    );
  }
}

class HomePage extends StatefulWidget {
  @override
  _HomePageState createState() => new _HomePageState();
}

class _HomePageState extends State<HomePage> {
  String xp = '0';

  @override
  Widget build(BuildContext context) {
    return new Scaffold(
      appBar: new AppBar(
        actions: <Widget>[
          new IconButton(
            icon: Icon(Icons.ac_unit),
            onPressed: () {},
          )
        ],
      ),
      body: new Container(
        padding: new EdgeInsets.only(top: 16.0),
        child: new ListView(
          children: <Widget>[
            new InkWell(
              onTap: () {},
              child: new InputDecorator(
                decoration: new InputDecoration(          
                  labelText: 'XP',
                  border: OutlineInputBorder()
                ),
                child: new Row(
                  mainAxisAlignment: MainAxisAlignment.spaceBetween,
                  mainAxisSize: MainAxisSize.min,
                  children: <Widget>[
                    new Text(this.xp),
                  ],
                ),
              ),
            )
          ],
        ),
      )
    );
  }
}

    像这样添加hintColor到你的主题,它应该更改OutlineInputBorder颜色 .

    ThemeData buildDarkTheme() {
      final ThemeData base = ThemeData();
      return base.copyWith(
        primaryColor: kBlack,
        accentColor: kYellow,
        scaffoldBackgroundColor: kBlackHalf,
        primaryTextTheme: buildTextTheme(base.primaryTextTheme, kWhite),
        primaryIconTheme: base.iconTheme.copyWith(color: kWhite),
        buttonColor: kYellow,
        hintColor: YOUR_COLOR,
        textTheme: buildTextTheme(base.textTheme, kWhite),    
        inputDecorationTheme: InputDecorationTheme(
          border: OutlineInputBorder(),
          labelStyle: TextStyle(
            color: kYellow,
            fontSize: 24.0
          ),
        ),
      );
    }

    从7月开始,您现在可以使用enabledBorder:

    new TextField(
      decoration: new InputDecoration(
        enabledBorder: const OutlineInputBorder(
          // width: 0.0 produces a thin "hairline" border
          borderSide: const BorderSide(color: Colors.grey, width: 0.0),
        ),
        border: const OutlineInputBorder(),
        labelStyle: new TextStyle(color: Colors.green),
        ...
      ),
    )

    这会将按钮的轮廓颜色更改为蓝色

    new OutlineButton(
       borderSide: BorderSide(color: Colors.blue),
    )
