Hello, I need help with the relation to dynamic domains in Odoo v 15

in Odoo v13 I used @api.onchange and return [('name','in',vals)]

Example:

@api.onchange('field_1')
def onchange_domain(self):
    vals = []
    objs = self.env['model'].search([])
    for obj in objs:
        vals.append(obj.code)    
    return {'domain' : {'field_2' : [('name', 'in', vals)]}}

In Odoo v14 the console says that the method is deprecated and in OCA I found the module called "web_domain_field" which has helped me a lot to manage dynamic domains using @api.depends and return json array to field char.

< --field name-=-"product_id_domain" invisible=-"1" -/- >
< --field-name-=-"product_id" domain=-"product_id_domain"-/- >

product_id_domain = fields.Char(
    compute="_compute_product_id_domain",
    readonly=True,
    store=False,
)
@api.multi
@api.depends('name')
def _compute_product_id_domain(self):
    for rec in self:
        rec.product_id_domain = json.dumps(
            [('type', '=', 'product'), ('name', 'like', rec.name)]
        )

But now in Odoo v15 there is no such module so reviewing the Odoo source code I can't find a simple way to handle this, someone who has already made a method that works in odoo v15 ?
