It seems like input() must be provided by classes using this trait. How about adding it as abstract method to this trait?

                if (!$base64Contents) {
                    return;
                }

                $tempFilePath = tempnam(sys_get_temp_dir(), $filename);

                // Store the contents using a stream, or by decoding manually
                if (Str::startsWith($base64Contents, 'data:') && count(explode(',', $base64Contents)) > 1) {
                    $source = fopen($base64Contents, 'r');
                    $destination = fopen($tempFilePath, 'w');

                    stream_copy_to_stream($source, $destination);

                    fclose($source);
                    fclose($destination);
                } else {
                    file_put_contents($tempFilePath, base64_decode($base64Contents, true));
                }

                $uploadedFile = new UploadedFile($tempFilePath, $filename, null, null, true);

                $body = $this->bodyParametersBag()->all();
                Arr::forget($body, $key);
                $this->bodyParametersBag()->replace($body);

                $files = $this->uploadFilesBag()->all();
                Arr::set($files, $key, $uploadedFile);
                $this->uploadFilesBag()->replace($files);
            }, null, false);
        });
    }
