Video Upload Functionality in Result.dart

The function within the result.dart file governs the video file upload process to the designated server. The function begins by defining the server's URL and the necessary HTTP headers. Subsequently, a MultipartRequest is employed to construct a POST request, facilitating the creation of a multi-part request specifically designed for file uploads.

Next, the function retrieves the headers and incorporates the selected video files utilizing MultipartFile.fromPath. The widget.videoFile.path variable represents the file path of the video intended for analysis within the JustDance section.

Following this, the request.send().then((r) async) command transmits the request to the server. A HTTP response callback, denoted by r within the parentheses, is then received, containing the statusCode. A statusCode of 200 signifies a successful request. Upon success, the result is stored in an ArrayList to preserve relevant information such as date and time. This information is then decoded and presented to the user in a comprehensible format. Lastly, the isLoading variable is set to false, indicating the function's completion.
