Unhandled Exception: FormatException: Invalid radix-10 number (at character 1) E/flutter (23894): null

  Unhandled Exception: FormatException: Invalid radix-10 number (at character 1)

E/flutter (23894): null

this Errro showing beacuse you not parsing  json parsing.

for json Parsing: - dart variable like char, double or int another json parsing like below showing here
Ex: - int.parse(json['demo'].toString);
just like parse the in the model class in flutter 

Solution:

  if (json['minimum_order_qty'] != null) {
      _minimumOrderQty = int.parse(json['minimum_order_qty'].toString());
    }

How to OCR Text Extraction in Flutter Using Google ML Kit

Image
Optical Character Recognition (OCR) is a powerful tool that enables apps to recognize and extract text from images. In this article, I'll walk you through how to implement OCR in a Flutter application using Google ML Kit. This can be particularly useful for creating document scanners, digitizing handwritten notes, or even converting printed text into digital form In this article, we will learn to recognize text from camera in Flutter. Text Recognition: This feature enables the identification of text from images or real-time camera input. The ML Kit Text Recognition API is capable of recognizing text in any Latin-based character set. For further details on Text Recognition, please refer to Google ML Kit's documentation. Using ML Kit for Text Recognition in Flutter For text recognition in Flutter, we are going to use the following Flutter plugins: google_ml_kit and camera. google_ml_kit: This plugin is used for text recognition and many other features. For more details, please...
