You can't get route name of previous page, so your options are:
您无法获取上一页的路线名称，因此您的选择是：
Check previous URL instead of a route name.
Use sessions. First, save route name:
session()->flash('previous-route', Route::current()->getName());
检查以前的 URL 而不是路由名称。
使用会话。首先，保存路由名称：
session()->flash('previous-route', Route::current()->getName());
Then check if session has previous-route:
然后检查会话是否有previous-route：
@if (session()->has(`previous-route`) && session(`previous-route`) == 'contacts')
Display something
@endif
- Use
GETparameters to pass route name.
- 使用
GET参数传递路由名称。
If I were you, I'd use sessions or would check previous URL.
如果我是你，我会使用会话或检查以前的 URL。

I've created a helper function like this.
我已经创建了一个这样的辅助函数。
/**
* Return whether previous route name is equal to a given route name.
*
* @param string $routeName
* @return boolean
*/
function is_previous_route(string $routeName) : bool
{
$previousRequest = app('request')->create(URL::previous());
try {
$previousRouteName = app('router')->getRoutes()->match($previousRequest)->getName();
} catch (\Symfony\Component\HttpKernel\Exception\NotFoundHttpException $exception) {
// Exception is thrown if no mathing route found.
// This will happen for example when comming from outside of this app.
return false;
}
return $previousRouteName === $routeName;
}

Simply you can do this to achieve it. I hope it helps
只需这样做，您就可以实现它。我希望它有帮助
In Controller:
在控制器中：
$url = url()->previous();
$route = app('router')->getRoutes($url)->match(app('request')->create($url))->getName();
if($route == 'RouteName') {
//Do required things
}
In blade file
在刀片文件中
@php
$url = url()->previous();
$route = app('router')->getRoutes($url)->match(app('request')->create($url))->getName();
@endphp
@if($route == 'RouteName')
//Do one task
@else
// Do another task
@endif
