Possible Fixes:

• One culprit for this is using GoogleFonts.getFont() method from flutter_flow_theme.dart, use local fonts instead.

Possible solution for this. See at Stackoverflow

Reverted back to default fonts to counter this issue. Lemme Know if this resolves this issue

Still used GoogleFonts SDK with the default fonts provided by Roboflow. Anyways, just downloaded the fonts from GoogleFonts, and it is located in the "assets/fonts" folder. Somehow, it resolved the issue.

Yet another issue raised with this code snippet from "home_page_widget":

Image.network(

                                        width:
                                            MediaQuery.sizeOf(context).width *
                                                1.0,
                                        height:
                                            MediaQuery.sizeOf(context).height *
                                                1.043,
                                        fit: BoxFit.cover,
                                      ),

this uses internet to load an image, which is not offline-friendly. Anyways, might try to solve this issue.
