Flutter plugin configuration issue - ios

Question

I am working on a flutter project which uses local database. For local database I am using sqflite plugin https://pub.dartlang.org/packages/sqflite. My application is working fine without installing sqflite. However, as soon as I install sqflite. It stops running for ios. I am receiving below errors.
import
1 error generated.
=== BUILD TARGET Runner OF PROJECT Runner WITH CONFIGURATION Debug ===

. And the strange thing is after this error, if I create new project of flutter it gives me below error.

And the application stops working. Here is the output of flutter doctor command.
