Hi Zubair,

Flow: A flow is an application that can execute logic, interact with the Salesforce database, call Apex classes, and collect data from users

Plugin: Plugin is a built-in interface that allows you to pass data between your organization and a specified flow.

Usage of flow in apex:
  • https://help.salesforce.com/apex/HTViewHelpDoc?id=vpm_designer_elements_apex.htm&language=en_US
  • https://developer.salesforce.com/docs/atlas.en-us.salesforce_vpm_guide.meta/salesforce_vpm_guide/vpm_distribute_system_apex.htm
Usage of Plugin in apex:
  • https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_process_plugin.htm
  • https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_process_plugin_using.htm
Note:Flow is an app which executes logic directly with salesforce database,in order to make a flow interact with salesforce database we make use of process.plugin interface.

Kindly mark this as best answer if it helps.

Best Regards,
