Unsupported version requirements. [{:modular_headers=>true}] is not valid..

I build the package in ios, but it throws this error.

[!] Failed to load 'flurry_analytics' podspec:
[!] Invalid `flurry_analytics.podspec` file: [!] Unsupported version requirements. [{:modular_headers=>true}] is not valid..

What is wrong about this ?

You can download this git, then put it in to the project folder
create plugin folder in the project folder
Next ,In pubspec.yaml:
add this
flurry_analytics:
path: ./plugin/flurry_analytics/

go to this git project folder,
Remove ",:modular_headers => true" in flurry_analytics.podspec

Then follow this link to do some action
