The procedure for transmitting an array to a NestJS API from a Flutter application involves the following steps:
Create an HTTP client in your Flutter application using the http package.
Define the array that you want to transmit as a Dart List.
Convert the Dart List to a JSON object using the built-in jsonEncode() method.
Send the JSON object to the NestJS API using an HTTP POST request.
In the NestJS API, create a POST endpoint that accepts JSON data.
Use the @Body() decorator to bind the incoming JSON data to a variable.
Convert the incoming JSON data to an array using the JSON.parse() method.
Process and store the array as required by your application.
Sample Flutter code:
import 'dart:convert';
import 'package:http/http.dart' as http;
void main() async {
final apiUrl = 'http://your-api-url.com/array-endpoint';
final List<int> sampleArray = [1, 2, 3, 4, 5];
final jsonData = jsonEncode(sampleArray);
final response = await http.post(apiUrl, body: jsonData);
}
Sample NestJS code:
import { Controller, Post, Body } from '@nestjs/common';
@Controller()
export class ArrayController {
@Post('/array-endpoint')
processArray(@Body() data: any) {
const array = JSON.parse(data);
// Process and store the array as required.
}
}
