Flutter线条绘制插件idkit_line的使用
Flutter线条绘制插件idkit_line的使用
idkit_line
是一个方便开发的工具包,用于在 Flutter 项目中扩展分隔线的需求。通过该插件,可以轻松创建实线、虚线、波浪线以及删除线等多种样式。
包扩展方法的使用案例
实线 (solid
)
IDKitLine.solid(),
const SizedBox(height: 20),
IDKitLine.solid(
color: Colors.red, // 设置颜色为红色
width: 300, // 设置宽度为300
height: 5, // 设置高度为5
thickness: 3, // 设置厚度为3
),
const SizedBox(height: 20),
IDKitLine.solid(
color: Colors.purple, // 设置颜色为紫色
width: 300, // 设置宽度为300
axis: Axis.vertical, // 垂直方向
height: 20, // 设置高度为20
)
虚线 (dotted
)
IDKitLine.dotted(),
const SizedBox(height: 20),
IDKitLine.dotted(
dashLength: 5, // 设置虚线段长度为5
interval: 3, // 设置间隔长度为3
thickness: 3, // 设置厚度为3
),
const SizedBox(height: 20),
IDKitLine.dotted(
width: 200, // 设置宽度为200
color: Colors.purple, // 设置颜色为紫色
dashLength: 5, // 设置虚线段长度为5
interval: 3, // 设置间隔长度为3
),
const SizedBox(height: 20),
IDKitLine.dotted(
dashLength: 5, // 设置虚线段长度为5
interval: 3, // 设置间隔长度为3
dottedType: DottedType.dash_dot, // 设置虚线类型为虚点线
),
const SizedBox(height: 20),
IDKitLine.dotted(
width: 200, // 设置宽度为200
color: Colors.purple, // 设置颜色为紫色
dashLength: 10, // 设置虚线段长度为10
interval: 3, // 设置间隔长度为3
thickness: 4, // 设置厚度为4
dottedType: DottedType.dash_dot, // 设置虚线类型为虚点线
)
波浪线 (wavy
)
IDKitLine.wavy(),
const SizedBox(height: 20),
IDKitLine.wavy(
color: Colors.red, // 设置颜色为红色
width: 300, // 设置宽度为300
),
const SizedBox(height: 20),
IDKitLine.wavy(
axis: Axis.vertical, // 设置为垂直方向
height: 200, // 设置高度为200
thickness: 4, // 设置厚度为4
a: 6, // 波浪参数a为6
w: 0.2, // 波浪参数w为0.2
)
删除线 (delete
)
IDKitLine.delete(
child: const Text('¥:10'), // 显示文本为¥:10
thickness: 2, // 设置厚度为2
color: Colors.red, // 设置颜色为红色
),
const SizedBox(height: 20),
IDKitLine.delete(
child: const Text('¥:10000000000'), // 显示文本为¥:10000000000
thickness: 4, // 设置厚度为4
color: Colors.purple, // 设置颜色为紫色
),

idkit_line
是一个用于在 Flutter 中绘制线条的插件。它提供了简单易用的 API,可以帮助开发者在 Flutter 应用中绘制各种类型的线条,包括直线、曲线、虚线等。
安装插件
首先,你需要在 pubspec.yaml
文件中添加 idkit_line
插件的依赖:
dependencies:
flutter:
sdk: flutter
idkit_line: ^1.0.0 # 请确保使用最新版本
然后运行 flutter pub get
来安装插件。
基本用法
以下是一些使用 idkit_line
插件绘制线条的基本示例。
1. 绘制直线
import 'package:flutter/material.dart';
import 'package:idkit_line/idkit_line.dart';
class LineExample extends StatelessWidget {
[@override](/user/override)
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('Line Example'),
),
body: Center(
child: Container(
width: 300,
height: 200,
child: CustomPaint(
painter: LinePainter(),
),
),
),
);
}
}
class LinePainter extends CustomPainter {
[@override](/user/override)
void paint(Canvas canvas, Size size) {
final line = Line()
..start = Offset(0, size.height / 2)
..end = Offset(size.width, size.height / 2)
..color = Colors.blue
..strokeWidth = 2.0;
line.paint(canvas);
}
[@override](/user/override)
bool shouldRepaint(CustomPainter oldDelegate) => false;
}
2. 绘制虚线
class DashedLinePainter extends CustomPainter {
[@override](/user/override)
void paint(Canvas canvas, Size size) {
final line = Line()
..start = Offset(0, size.height / 2)
..end = Offset(size.width, size.height / 2)
..color = Colors.red
..strokeWidth = 2.0
..dashPattern = [10, 5]; // 设置虚线模式
line.paint(canvas);
}
[@override](/user/override)
bool shouldRepaint(CustomPainter oldDelegate) => false;
}
3. 绘制曲线
class CurveLinePainter extends CustomPainter {
[@override](/user/override)
void paint(Canvas canvas, Size size) {
final path = Path()
..moveTo(0, size.height / 2)
..quadraticBezierTo(size.width / 2, size.height, size.width, size.height / 2);
final line = Line()
..path = path
..color = Colors.green
..strokeWidth = 3.0;
line.paint(canvas);
}
[@override](/user/override)
bool shouldRepaint(CustomPainter oldDelegate) => false;
}
