Access Application Temporary directory data for another app

I'm using flutter for develop mobile application. There is pdf generation process inside app after generate pdf need to open os default share options. For that I'm use flutter share-extend library.

To get temporary location I use path provider library. Using this I get temp location and store pdf on that location.

Future<String> get localPath async {
Directory tempDir = await getTemporaryDirectory();
return tempDir.path;
}

This is hoe I use share extend to open default share options.

var dir = await localPath;
File shareFile = File("$dir/$fileNameToGenerate.pdf");
ShareExtend.share(shareFile.path, "file",
    sharePanelTitle: sharePanelTitle, subject: shareSubject);

It gives options to share and no problem with process. But there is security exception in the console.

E/DatabaseUtils(15076): java.lang.SecurityException: Permission Denial: reading com.zt.shareextend.ShareExtendProvider uri content://com.example.agile_iq.shareextend.fileprovider/%252Fdata%252Fuser%252F0%252Fcom.example.agile_iq%252Fcache%252FAgileiq_Assessment_202005181731.pdf from pid=12492, uid=1000 requires the provider be exported, or grantUriPermission()

In manifest file I tried to import provider.

<provider
        android:name="androidx.core.content.FileProvider"
        android:authorities="${applicationId}.provider"
        android:exported="false"
        android:grantUriPermissions="true">
        <meta-data
            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/file_provider_paths" />

But after import this project atleast not building. Is there any solution for this.
