In case anybody else gets this error and is routed here:

You will see this error if you've had a bad merge on your Podfile.lock. Specifically, when I saw the issue, it was because there was a trailing colon ":" on a pod line like so:

...
  - SomePod (1.0.0):
    - SomeDependency
  - TheProblemLine (0.0.1):
  - YetAnotherPod (2.0.0):
    - MoreDepdencies
...

You can delete that errant line and then re-run pod install to recreate a working Podfile.lock.

@cchamb-gh Thanks!
You saved my day!

@cchamb-gh 's solution really worked perfectly for me. I deleted the unnecessary semi-colon (which is used to indicate that the following packages, which are normally indented, are dependencies) and ran pod install. The dependency was added automatic and everything worked.

I deleted Podfile.lock and ran pod install and it didn't solve it for me.

flutter clean
flutter pub get
pod install

The @cchamb-gh is right.
You only need to remove the semi-colon from items without children.

For example: On this case, you only need to remove the semi-colon from TheProblemLine (0.0.1).

...
  - SomePod (1.0.0):
    - SomeDependency
  - TheProblemLine (0.0.1):
  - YetAnotherPod (2.0.0):
    - MoreDepdencies
...
