I followed some answers from here that are similar to my issues. But unfortunately, the error is not removed. That is why I asked here again.

This is an old versioned React Native project where react-native-document-picker version was 2.1.0. When I upgraded the version to 8.0.0, the error shows as the following screenshot:

The current files are as like below;

android/settings.gradle

...    
include ':react-native-document-picker'
project(':react-native-document-picker').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-document-picker/android')
...

android/app/build.gradle

dependencies {
    implementation fileTree(dir: "libs", include: ["*.jar"])
    ...
    ...
    implementation project(':react-native-document-picker')
}

import {DocumentPicker, DocumentPickerUtil} from 'react-native-document-picker';

    pressOnAttach() {

        this.refs.NoticeDescription.blur();
        setTimeout(() => {

                filetype: [DocumentPickerUtil.allFiles()],
            }, (error, res) => {
                if (error === null) {
                    setTimeout(() => {
                        if (!this.checkFileExtension(res.fileName)) {
                            alert(AppText.VALID_EXTENSION_MESSAGE)
                        } else {
                            this.generateList(res.uri, res.fileName, res.fileSize);
                        }
                    }, 1000)
                }
            });
        }, 1000)
    }

When I console.log the DocumentPicker and DocumentPickerUtil, it returns undefined always.

Could anyone help me please to fix this issue? Thanks in advance!

CodePudding user response：

The reason you are getting DocumentPicker undefined is the react-native-document-picker version 8.0.0 has been updated since version 2.1.0 which code you've posted.

According to the library doc, you have to import the DocumentPicker differently. And the util DocumentPickerUtil is also not available to the updated version. For react-native-document-picker version 8.0.0 you have to import in the following way

import DocumentPicker, { types } from 'react-native-document-picker';

And also DocumentPicker.show method is no longer available you have to use the DocumentPicker.pick method.
