@bhavaniravi could you update the PR desc to have "part of issue-xyz" instead of "fixes issue-xyz"?

Keep the BaseOperator from version_compat:

airflow/providers/google/src/airflow/providers/google/version_compat.py

Lines 38 to 48 in f8f976d

	# Version-compatible imports
	# BaseOperator: Use 3.1+ due to xcom_push method missing in SDK BaseOperator 3.0.x
	# This is needed for DecoratedOperator compatibility
	if AIRFLOW_V_3_1_PLUS:
	from airflow.sdk import (
	BaseHook,
	BaseOperator,
	)
	else:
	from airflow.hooks.base import BaseHook # type: ignore[attr-defined,no-redef]
	from airflow.models import BaseOperator
