If you intend to arrive in the UK before 29th March:
You can apply for a Family Permit in France, for which you are eligible as the spouse of a EU national intending to move to the UK.
Alternatively, if you have an Article 10 card issued in France, as the spouse of a French national, you can come to the UK without a Family Permit (
https://www.gov.uk/check-uk-visa/y/india/family/yes). Have your marriage certificate with you to show at border control.
Then, once you are in the UK you can either apply for
a) a Residence Card (only eligible if you arrive in the UK before 29th March 2019) or
b) Pre-Settled status.
If you intend to arrive in the UK after 29th March, the situation is much more uncertain, as:
If The UK leaves the EU with a deal, you have until the 31st December 2020 to come to the UK, and until 30th June 2021 to apply for Pre-Settled Status only.
If the UK leaves the EU with no-deal, you you will not be eligible to apply for any of the above. You and your wife will need instead to apply for the proposed European Temporary Leave to Remain route, which will not entitle you to stay in the UK more than 3 years, after which you need to apply to stay through a new immigration system.
