Getting started

Follow these simple steps to get started with FileCase, for detailed example see example folder.

• Create an instance of FileCaseController and provide a unique string as tag

final firstController = FileCaseController(
      filePickerOptions: FilePickerOptions(type: FileType.any),
      tag: 'controller1');

Pass FilePickerOptions to customize pickFiles functionality from file_picker. For information about FilePickerOptions, hover over the parameters and see the docs.

• Use the FileCase widget in your UI and pass the same tag string as for the FileCaseController

const FileCase(
              tag: 'controller1',
            ),

• Use the FileUploadIconButton or FileUploadButton in your UI to be able to pick files.
  Pass the same tag string as for the corresponding FileCaseController and FileCase.

const FileUploadIconButton(tag: 'controller1'),

OR

const FileUploadButton(tag: 'controller1'),

Usage

Sending files over an API

• Using FormData
  
  FormData is available in Dio

import 'package:dio/dio.dart' as dio;

class NetworkService {

  final url = 'http://127.0.0.1:8000/files'; // local host url

  uploadFiles(List<PlatformFile> platformFiles) async {

    final formData = dio.FormData();

    formData.files.addAll(platformFiles.map((platformFile) => MapEntry(
        'files',
        dio.MultipartFile.fromBytes(platformFile.bytes as List<int>,
            filename: platformFile.name))));

    final response = await dio.Dio().post(url, data: formData);
  }
}

• Using MultipartRquest
  
  MultipartRequest is available in http

import 'package:http/http.dart' as http;

class NetworkService {

  final url = 'http://127.0.0.1:8000/files'; // local host url

  uploadFiles(List<PlatformFile> platformFiles) async {

    final response =
          http.MultipartRequest('POST', Uri.parse(url + '/fileupload'))

            //For single file - Remove this comment for usage
            ..files.add(http.MultipartFile.fromBytes(
                'file', files.first.bytes as List<int>,
                filename: 'newupload.txt'))

            //For multiple files - Remove this comment for usage
            ..files.addAll(files.map((file) => http.MultipartFile.fromBytes(
                'file', file.bytes as List<int>,
                filename: file.name)))

      final finalResponse = await response.send();
  }
}

http.MultipartRequest does not return a response body.
