Cloud_firestore_odm gives bootstrap exception error

[dhanesh12twice]

In contribution guidelines, one has to install melos package to track the dependencies. When running the command 'melos bs --sdk-path=PATH" . FlutterFire_internals, Cloud_firestore packages are installed successfullly. But cloud_firestore_odm package is failed everytime and showing BootstrapExceptionError. Ive searched on net but found helpless. Could anyone there to help? Thank you
