如何使用yii2 i2-dashboard？

composer require --prefer-dist lucianobaraglia/yii2-i2-dashboard "*"

return [
    // ...
    'modules' => [
        // ...
        'i2Dashboard' => [
            'class' => 'luciobaraglia\yii2I2Dashboard\I2Dashboard',
            'layout' => '@app/views/layouts/main', // 可选，指定布局文件
            'access' => ['@'], // 可选，指定访问权限
        ],
    ],
    // ...
];

php yii generate:controller Dashboard

namespace app\controllers;

use Yii;
use yii\web\Controller;
use lucianobaraglia\yii2I2Dashboard\I2Dashboard;

class DashboardController extends Controller
{
    public function actionIndex()
    {
        $dashboard = new I2Dashboard();
        $dashboard->addWidget('luciobaraglia\yii2I2Dashboard\widgets\TextWidget', [
            'title' => 'Hello, World!',
            'content' => 'This is a simple text widget.',
        ]);

        return $this->render('index', [
            'dashboard' => $dashboard,
        ]);
    }
}

<?php
use lucianobaraglia\yii2I2Dashboard\I2Dashboard;

/* @var $this yii\web\View */
/* @var $dashboard I2Dashboard */

$this->title = 'My Dashboard';
$this->params['breadcrumbs'][] = $this->title;
?>
<div class="dashboard-default-index">
    <?= $dashboard->render() ?>
</div>

$dashboard->addWidget('luciobaraglia\yii2I2Dashboard\widgets\ChartWidget', [
    'title' => 'My Chart',
    'type' => 'bar',
    'data' => [
        ['January', 10],
        ['February', 20],
        ['March', 30],
        // ...
    ],
]);
