In the file payment_stripe_template.xml of the stripe plugin we can find the line of code :
t-attf-id="o_stripe_express_checkout_container_{{provider_sudo.id}}"
t-att-data-provider-id=".id"
t-att-data-provider-code=".code"
t-att-data-stripe-publishable-key="provider_sudo._stripe_get_publishable_key()" t-att-data-country-code="provider_sudo.company_id.country_id.code" class="w-100 mt-2"/>
I was wondering how was the "t-att-data-stripe-publishable-key" created and how it was calling the function to replicate it in my own plugin
