我可以将 flutter 资产用于 iOS 上的本地通知附件吗

Question

I am using the flutter_local_notifications package to show notifications in my flutter app. I would like to show an image with my notifications on iOS by adding the image to the "attachments" array in IOSNotificationDetails.

final iosNotificationDetails = IOSNotificationDetails(
    attachments: [IOSNotificationAttachment('assets/image.png')],
);

I have seen the example to download the image from a URL and save it in the application documents directory, but would like to know if there is a way to either load an image directly from the flutter assets or from a file in my iOS project.

Answer 1

import 'dart:async'; import 'dart:io';

import 'package:flutter/services.dart' show rootBundle; import 'package:path_provider/path_provider.dart';

Future getImageFileFromAssets(String path) async { final byteData = await rootBundle.load('assets/$path');

final file = File('${(await getTemporaryDirectory()).path}/$path'); await file.writeAsBytes(byteData.buffer.asUint8List(byteData.offsetInBytes, byteData.lengthInBytes));

return file; }
