My flutter application throws this exception in runtime.

main.dart
Directory tp = await getTemporaryDirectory();
File tempFile = File('${tp.path}/flutter.pdf');
ByteData bd = await rootBundle.load('assets/flutter.pdf');
tempFile=await tempFile.writeAsBytes(bd.buffer.asUint8List(), flush: true);

# The following defines the version and build number for your application.
# A version number is three numbers separated by dots, like 1.2.43
# followed by an optional build number separated by a +.
# Both the version and the builder number may be overridden in flutter
# build by specifying --build-name and --build-number, respectively.
# In Android, build-name is used as versionName while build-number used as versionCode.

# To add assets to your application, add an assets section, like this:
assets:
- assets/flutter.pdf
# - images/a_dot_ham.jpeg
# An image asset can refer to one or more resolution-specific "variants", see
# https://flutter.dev/assets-and-images/#resolution-aware.
# For details regarding adding assets from package dependencies, see
# https://flutter.dev/assets-and-images/#from-packages
# To add custom fonts to your application, add a fonts section here,
# in this "flutter" section. Each entry in this list should have a
# "family" key with the font family name, and a "fonts" key with a
# list giving the asset and other descriptors for the font. For
# example:
# fonts:
# - family: Schyler
# fonts:
# - asset: fonts/Schyler-Regular.ttf
# - asset: fonts/Schyler-Italic.ttf
# style: italic
# - family: Trajan Pro
# fonts:
# - asset: fonts/TrajanPro.ttf
# - asset: fonts/TrajanPro_Bold.ttf
# weight: 700
#
# For details regarding fonts from package dependencies,
# see https://flutter.dev/custom-fonts/#from-packages
Already done this:
1.flutter clean and flutter run
2.import this packages
1.package:path_provider/path_provider.dart
2.dart:io
3.dart:async
Thanks in Advance

On 16.03.2022 i had this problem with path_provider^2.0.9 when used it in background service. Adding these lines in pubspec.yaml fixed the problem:
dependency_overrides:
path_provider_android: 2.0.11

Answer 2

My similar problem (MissingPluginException) occured only with the release build.
It was solved by this line:
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'),'proguard-rules.pro'
according to
