I have been running my flutter apps on simulators and recently I had to build an IPA file to test on a physical device. When I try to install on the device it tells me "App cannot be installed because its integrity can not be verified". I did my research and found out that many people who had this issue solved it by adding the UDID of the device to their Apple Developer Accounts. I have added the UDID but I am still getting the same error.
