所以我想从model和controller返回一些字符串，但它总是说未定义的变量，尽管当我用dd($检查时它成功通过了a) 和 dd($b)。我做错了什么？

about.blade：

@extends('layout.template');
@section('homeContainer');

<p> {{ $a }} </p>
<br>
<p>{{ $b }}</p>
@endsection

关于控制器：

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Models\AboutModel;

class AboutController extends Controller
{
    //
    public static function info(){
        $a = AboutModel::info();
        $b = "This data is from controller";
    

        return view('about', compact('a', 'b'));
    }
}

关于模型：

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class AboutModel extends Model
{
    use HasFactory;
    
    public static function Info(){
        $a = "This value is from model";
        return $a;
    }
}

路线：

<?php


use Illuminate\Support\Facades\Route;
use App\Http\Controllers\AboutController;

/*

| Here is where you can register web routes for your application. These

*/

Route::get('/', function () {
    return view('welcome');
});



Route::get('/about', function () {
    return view('about', [
        "name" => AboutController::info(),
    ]);
});
