# Alterar flag do marco

O esquema ideal para este endpoint.

## Esquema

Isso valida um formulário de escrow usando Zod, incluindo endereços de carteira, propriedades de flag de alteração e índice de marco.

```typescript
import { isValidWallet } from "@/helpers/valid-data.helper";
import { z } from "zod";

export const formSchema = z.object({
  contractId: z.string().min(1, "ID do contrato é obrigatório"),
  milestoneIndex: z.string().min(1, "O índice do marco é obrigatório"),
  newFlag: z.boolean(),
  approver: z
    .string()
    .min(1, {
      message: "Aprovação é obrigatória.",
    })
    .refine((value) => isValidWallet(value), {
      message: "O aprovador deve ser uma carteira válida.",
    }),
});

```

## Hook Personalizado

Isso contém toda a lógica do formulário, incluindo validação de esquema, função onSubmit e outros estados e funcionalidades.

```typescript
import { useEscrowContext } from "@/providers/escrow.provider";
import { useState } from "react";
import { useForm } from "react-hook-form";
import { zodResolver } from "@hookform/resolvers/zod";
import { z } from "zod";
import { formSchema } from "../schemas/change-milestone-flag-form.schema";
import { escrowService } from "../services/escrow.service";
import { toast } from "sonner";
import { Escrow, Milestone } from "@/@types/escrows/escrow.entity";
import { EscrowRequestResponse } from "@/@types/escrows/escrow-response.entity";
import { ChangeMilestoneFlagPayload } from "@/@types/escrows/escrow-payload.entity";

export const useChangeMilestoneFlagForm = () => {
  const { escrow } = useEscrowContext();
  const { setEscrow } = useEscrowContext();
  const [loading, setLoading] = useState(false);
  const [response, setResponse] = useState<EscrowRequestResponse | null>(null);

  // Marcos padrão caso o escrow seja indefinido
  const milestones = escrow?.milestones || [
    { description: "Initial setup", status: "pending" },
    { description: "Development phase", status: "pending" },
  ];

  const form = useForm<z.infer<typeof formSchema>>({
    resolver: zodResolver(formSchema),
    defaultValues: {
      contractId: escrow?.contractId || "CAZ6UQX7DEMO123",
      milestoneIndex: "",
      newFlag: true,
      approver: escrow?.roles.approver || "GAPPROVER123456789",
    },
  });

  const onSubmit = async (payload: ChangeMilestoneFlagPayload) => {
    setLoading(true);
    setResponse(null);

    try {
      /**
       * Chamada à API usando o serviço de escrow
       * @Nota:
       * - Precisamos especificar o endpoint e o método
       * - Precisamos especificar que returnEscrowDataIsRequired é false
       * - O resultado será um EscrowRequestResponse
       */
      const result = (await escrowService.execute({
        payload,
        endpoint: "/escrow/change-milestone-approved-flag",
        method: "post",
        returnEscrowDataIsRequired: false,
      })) as EscrowRequestResponse;

      /**
       * @Respostas:
       * result.status === "SUCCESS"
       * - Escrow atualizado com sucesso
       * - Definir o escrow no contexto
       * - Mostrar um toast de sucesso
       *
       * result.status !== "SUCCESS"
       * - Mostrar um toast de erro
       */
      if (result.status === "SUCCESS") {
        const escrowUpdated: Escrow = {
          ...escrow!,
          milestones: escrow!.milestones.map((milestone: Milestone, index) =>
            index === Number(payload.milestoneIndex)
              ? { ...milestone, approvedFlag: payload.newFlag }
              : milestone
          ),
        };

        setEscrow(escrowUpdated);

        toast.info(
          `Milestone index - ${payload.milestoneIndex} has been approved`
        );
        setResponse(result);
        form.reset();
      }
    } catch (err) {
      toast.error(
        err instanceof Error ? err.message : "Ocorreu um erro desconhecido"
      );
    } finally {
      setLoading(false);
    }
  };

  return { form, milestones, loading, response, onSubmit };
};

```

## Formulário

Este formulário é construído com react hook form. Usamos o hook personalizado e o esquema Zod mencionados anteriormente.

```typescript
"use client";

import { Button } from "@/components/ui/button";
import { Input } from "@/components/ui/input";
import { Switch } from "@/components/ui/switch";

  Form,
  FormField,
  FormItem,
  FormLabel,
  FormControl,
  FormMessage,
} from "@/components/ui/form";
import {
  Select,
  SelectContent,
  SelectItem,
  SelectTrigger,
  SelectValue,
} from "@/components/ui/select";
import { useChangeMilestoneFlagForm } from "../../hooks/change-milestone-flag-form.hook";
import { useEscrowContext } from "@/providers/escrow.provider";
import { ResponseDisplay } from "@/components/utils/response-display";

export function ChangeMilestoneFlagForm() {
  const { form, milestones, loading, response, onSubmit } =
    useChangeMilestoneFlagForm();
  const { escrow } = useEscrowContext();

  return (

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.trustlesswork.com/trustless-work/v1-pt/dapps-oss/escrow-lab/formularios/alterar-flag-do-marco.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
