Setup

Since this package makes use of file_picker package, for platform specific setup follow this instructions

Basic use

 import 'package:flutter_form_builder/flutter_form_builder.dart';
 import 'package:form_builder_file_picker/form_builder_file_picker.dart';

  FormBuilderFilePicker(
    name: "images",
    decoration: InputDecoration(labelText: "Attachments"),
    maxFiles: null,
    previewImages: true,
    onChanged: (val) => print(val),
    typeSelectors: [
      TypeSelector(
        type: FileType.any,
        selector: Row(
          children: <Widget>[
            Icon(Icons.add_circle),
            Padding(
              padding: const EdgeInsets.only(left: 8.0),
              child: Text("Add documents"),
            ),
          ],
        ),
      ),
    ],
    onFileLoading: (val) {
      print(val);
    },
  ),

Specific uses

On mobile platforms the file picker will open a default document picker if used with FileType.any. If you want to be able to pick documents and images in the same form field, you will need to define different file types and different selectors. To achieve this use the typeSelectors parameter. This way the user will see two buttons to open a file picker for documents and a file picker for the photos gallery.

For example:

FormBuilderFilePicker(
  name: "attachments",
  previewImages: false,
  allowMultiple: true,
  withData: true,
  typeSelectors: [
    TypeSelector(
      type: FileType.any,
      selector: Row(
        children: <Widget>[
          Icon(Icons.add_circle),
          Padding(
            padding: const EdgeInsets.only(left: 8.0),
            child: Text("Add documents"),
          ),
        ],
      ),
    ),
    if (!kIsWeb)
      TypeSelector(
        type: FileType.image,
        selector: Row(
          children: <Widget>[
            Icon(Icons.add_photo_alternate),
            Padding(
              padding: const EdgeInsets.only(left: 8.0),
              child: Text("Add images"),
            ),
          ],
        ),
      ),
    ],
  )
