When I run:
pod outdated
on IOS to determine any pods that are outdated I get the following result:
....
Analyzing dependencies
The color indicates what happens when you run `pod update`
<green> - Will be updated to the newest version
<blue> - Will be updated, but not to the newest version because of specified version in Podfile
<red> - Will not be updated because of specified version in Podfile
The following pod updates are available:
- Flutter 1.0.0 -> 1.0.0 (latest version 1.3.300)
- Protobuf 3.9.2 -> 3.9.2 (latest version 3.10.0-rc1)
While version 1.0.0 of Flutter (in red) seems to be okay at the moment on IOS can someone please suggest how I can update this Pod?
I have upgraded Flutter using:
/Users/bob/Downloads/flutter/bin/flutter upgrade
The above command seems to make no difference per the pod version noted above. I would prefer everything be at the latest version but if it is not necessary knowing that information would be helpful as well.
Using:
/Users/bob/Downloads/flutter/bin/flutter doctor -v

The problem comes from the podhelper.rb script (YOUR_PATH//flutter/packages/flutter_tools/bin/podhelper.rb). It generates a 'fake' Flutter.podspec file but it hardcodes the 1.0.0 podspec.
Resolve this by editing lines 155-190 of podspec.rb (for iOS app), replacing the json definitions for the podspec with the version you want to move to from the CocoaPods repo (e.g. here for v2.5). Run pod update and it will update to 2.5.
The next section in the script repeats the same error for macOS apps so you may need to repeat for lines 193-228.
