Flutter throws dependency error not flutter 2

Question

I have a flutter project that uses imagepicker as a pub package, when I run the project I get the following error, this happened to me after I changed my mac to m1, I have already followed several guides about it but I can't solve it, pod packages are installed but running on ios does not start, what can it be?

Error:

Running pod install...                                           1,271ms

Solution

If you are using getMultiImage you have to upgrade your deployment target in Xcode to iOS14.

Open flutter project in Xcode Runner > General > Deployment Info > iOS14
