Question

I am using sql developer version 21.( Recently installed) I can't access the view sqls/ definition from the view tab. I can accessor see the view text from " details" tab but not from the "Sql" tab.
I don't have admin privilege.
The same user can view view sqls from sqldeveloper version 18...

In older versions of SQL Developer we had a 'try to generate DDL' method for when DBMS_METADATA.GET_DLL() wasn't available.
This wasn't a maintainable position. The 'internal generator' has multiple issues, and we decided to deprecate it.
In order to see the DDL for an object, you need for the DBMS_METADATA package to be available to your user, for said object.
What SQL Developer runs to get you the DDL for a VIEW, is approx:
SELECT
dbms_metadata.get_ddl(
'VIEW',
:name,
:owner
)
FROM
dual
UNION ALL
SELECT
dbms_metadata.get_ddl(
'TRIGGER',
trigger_name,
owner
)
FROM
dba_triggers
WHERE
table_owner = :owner
AND table_name = :name
UNION ALL
SELECT
dbms_metadata.get_dependent_ddl(
'COMMENT',
table_name,
owner
)
FROM
(
SELECT
table_name,
owner
FROM
dba_col_comments
WHERE
owner = :owner
AND table_name = :name
AND comments IS NOT NULL
UNION
SELECT
table_name,
owner
FROM
sys.dba_tab_comments
WHERE
owner = :owner
AND table_name = :name
AND comments IS NOT NULL
)
In a development environment, a developer should have full access to their application, and I would extend that to the data dictionary. It's another reason I advocate developers have their own private database (Docker/VirtualBox/Cloud/whatever).
If that fails, consult your data model.
If you don't have a data model, that's another problem.
If that fails, you do have workaround of checking the Details panel for a view to get the underlying SQL.

Just FYI, I searched for an answer to this problem and found no actual solutions.
thatjeffsmith was correct that earlier versions of SQLDeveloper do not have this issue or requirement of higher privs to view the SQL tab. However, the link he provided was version 20.4 and it sill did not display the SQL tab correctly. I reverted back to 3.1.07 (which I happened to be using prior to upgrading my laptop) and using the same login to the same instance it does display the SQL for views, full definition, without issue. This is against a 12c Oracle database.
