FilamentPHP 小组件生成技能

概述

此技能可生成 FilamentPHP v4 仪表板小组件，包括统计概览小组件、图表小组件、表格小组件和自定义小组件。

文档参考

重要： 生成小组件前，请先阅读：

• /home/mwguerra/projects/mwguerra/claude-code-plugins/filament-specialist/skills/docs/references/widgets/

创建小组件

使用 Artisan 生成

# Basic widget
php artisan make:filament-widget StatsOverview

# Stats overview widget
php artisan make:filament-widget StatsOverview --stats-overview

# Chart widget
php artisan make:filament-widget RevenueChart --chart

# Table widget
php artisan make:filament-widget LatestOrders --table

# Resource widget
php artisan make:filament-widget PostStats --resource=PostResource

输出

生成的小组件包括：

1. 正确选择小组件类型
2. 数据获取方法
3. 图表配置
4. 样式和布局
5. 交互功能（筛选器、操作）
6. 性能优化
