# Change Dispute Flag

## Schema

This validates an escrow form using Zod, including wallet addresses.

```typescript
import { z } from "zod";

export const formSchema = z.object({
  contractId: z.string().min(1, "Contract ID is required"),
  signer: z.string().min(1, "Signer address is required"),
});

```

## Custom Hook

This contains all the form logic, including schema validation, onSubmit function and others states and functionalities.

```typescript
import { useEscrowContext } from "@/providers/escrow.provider";
import { useWalletContext } from "@/providers/wallet.provider";
import { zodResolver } from "@hookform/resolvers/zod";
import { useState } from "react";
import { useForm } from "react-hook-form";
import { z } from "zod";
import { formSchema } from "../schemas/start-dispute-form.schema";
import { escrowService } from "../services/escrow.service";
import { Escrow } from "@/@types/escrows/escrow.entity";
import { toast } from "sonner";
import { EscrowRequestResponse } from "@/@types/escrows/escrow-response.entity";
import { StartDisputePayload } from "@/@types/escrows/escrow-payload.entity";

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

  const form = useForm<z.infer<typeof formSchema>>({
    resolver: zodResolver(formSchema),
    defaultValues: {
      contractId: escrow?.contractId || "",
      signer: walletAddress || "Connect your wallet to get your address",
    },
  });

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

    try {
      /**
       * API call by using the escrow service
       * @Note:
       * - We need to specify the endpoint and the method
       * - We need to specify that the returnEscrowDataIsRequired is false
       * - The result will be an EscrowRequestResponse
       */
      const result = (await escrowService.execute({
        payload,
        endpoint: "/escrow/change-dispute-flag",
        method: "post",
        returnEscrowDataIsRequired: false,
      })) as EscrowRequestResponse;

      /**
       * @Responses:
       * result.status === "SUCCESS"
       * - Escrow updated successfully
       * - Set the escrow in the context
       * - Show a success toast
       *
       * result.status !== "SUCCESS"
       * - Show an error toast
       */
      if (result.status === "SUCCESS") {
        const escrowUpdated: Escrow = {
          ...escrow!,
          flags: {
            disputeFlag: true,
          },
        };

        setEscrow(escrowUpdated);

        toast.info("Dispute Started");
        setResponse(result);
      }
    } catch (err) {
      toast.error(
        err instanceof Error ? err.message : "An unknown error occurred"
      );
    } finally {
      setLoading(false);
    }
  };

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

```

## Form

This form is built with react hook form. We use the custom hook and zod schema mentioned before.

```typescript
"use client";

import { Button } from "@/components/ui/button";
import { Input } from "@/components/ui/input";
import {
  Form,
  FormControl,
  FormField,
  FormItem,
  FormLabel,
  FormMessage,
} from "@/components/ui/form";
import { useEscrowContext } from "@/providers/escrow.provider";
import { useStartDisputeForm } from "../../hooks/start-dispute-form.hook";
import { ResponseDisplay } from "@/components/utils/response-display";

export function StartDisputeForm() {
  const { form, loading, response, onSubmit } = useStartDisputeForm();
  const { escrow } = useEscrowContext();

  return (
    <div className="space-y-6">
      <Form {...form}>
        <form onSubmit={form.handleSubmit(onSubmit)} className="space-y-4">
          <FormField
            control={form.control}
            name="contractId"
            render={({ field }) => (
              <FormItem>
                <FormLabel>Contract / Escrow ID</FormLabel>
                <FormControl>
                  <Input
                    placeholder="CAZ6UQX7..."
                    {...field}
                    disabled={!!escrow?.contractId}
                  />
                </FormControl>
                <FormMessage />
              </FormItem>
            )}
          />

          <FormField
            control={form.control}
            name="signer"
            render={({ field }) => (
              <FormItem>
                <FormLabel>Signer Address</FormLabel>
                <FormControl>
                  <Input disabled placeholder="GSIGN...XYZ" {...field} />
                </FormControl>
                <FormMessage />
              </FormItem>
            )}
          />

          <Button type="submit" className="w-full" disabled={loading}>
            {loading ? "Starting Dispute..." : "Start Dispute"}
          </Button>
        </form>
      </Form>

      <ResponseDisplay response={response} />
    </div>
  );
}

```

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.trustlesswork.com/trustless-work/oss-dapps/escrow-lab/forms/change-dispute-flag.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
