Error: The argument type 'File/*1*/' can't be assigned to the parameter type 'File/*2*/'.

I get this error on GitHub CI with a project of mine but builds locally.

lib/widgets/user_drawer.dart:96:33:
Error: The argument type 'File/*1*/' can't be assigned to the parameter type 'File/*2*/'.
 - 'File/*1*/' is from 'dart:io'.
 - 'File/*2*/' is from 'package:flutter_svg/src/utilities/_file_none.dart' ('/opt/hostedtoolcache/flutter/3.19.6-stable/x64/.pub-cache/hosted/pub.dev/flutter_svg-2.0.10+1/lib/src/utilities/_file_none.dart').
                                File(app.icon!),
