How to update IMAGE in laravel?

I have tried many ways to update image but its not working at all though I can update other data except image.

code for saving Image and other inputs

 public function store(Request $request)
{

    $fileName = null;
    if($request->file('image')){
        $fileName = strtotime(Carbon::now());
        $fileName = $fileName.".".$request->file('image')->extension();
        $uploadPath = (public_path($this->uploadPath."/".$fileName));
        move_uploaded_file($request->file('image'), $uploadPath);
    }
        $data = $request->all();
        $data['image'] = $fileName;
    if(Covidrecord::create($data))
    {
        return redirect()->route('store')->with(['msg'=>"User create successfully"]);
        return redirect()->route('store')->withError(['msg'=>"User cannot be registerd at the moment"]);

    }
}

Code for UPDATING

  public function update(Request $request,Covidrecord $covidrecord, $id)
    {
        $data = Covidrecord::find($id);

    $fileName = null;
    if($request->file('image')){
        $fileName = strtotime(Carbon::now());
        $fileName = $fileName.".".$request->file('image')->extension();
        $uploadPath = (public_path($this->uploadPath."/".$fileName));
        move_uploaded_file($request->file('image'), $uploadPath);
    }
        $data = $request->all();
        $data['image'] = $fileName;
        $covidrecord->update($request->all());

        return redirect()->route('allrecord')->with(['msg'=>"User create successfully"]);

}

Blade
