in order to use a new plugin, I had to update my cordova version to 9.0.0, and I also updated my android version to 28.
My problem is now I can't compile my project because of the cordova plugin "localnotification" (https://github.com/katzer/cordova-plugin-local-notifications).
I have a bunch of errors (maybe 150/200) related to android support library v4, like :
error: package android.support.v4.content does not exist
or
cannot find symbol public class AssetProvider extends FileProvider {
^
Because I updgraded android, I had to migrate to androidX too. I did it by adding this in gradle.properties :
android.enableJetifier=true
android.useAndroidX=true
But now I'm unable to compile my app without all these errors above. I found something saying that we should add these lines in the .gradle of the plugin :
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support:support-v4:28.0.0'
I did it without success.
Any other ideas ?
Thanks in advance !

So i am trying to get started with riverpod and creating a new flutter project with the "click and counter" default sample.
As soon as I add on the pubspec
flutter_hooks: ^0.18.0
hooks_riverpod: ^2.0.0
And
import 'package:hooks_riverpod/hooks_riverpod.dart';
I get this error on the debug console and can't figure it out what is the problem
: Error: Method not found: 'Error.throwWithStackTrace'.
../…/framework/provider_base.dart:904
Error.throwWithStackTrace(error, chain);
^^^^^^^^^^^^^^^^^^^
: Error: A non-null value must be returned since the return type 'Never' doesn't allow null.
../…/framework/provider_base.dart:898
Never _rethrowProviderError(Object error, StackTrace stackTrace) {
^
Error.throwWithStackTrace was added in Dart 2.16 (Flutter version 2.10 from Feb 8, 2022).
https://api.flutter.dev/flutter/dart-core/Error/throwWithStackTrace.html
(Check the #Since annotation.)
If your Flutter/Dart version is below that, you'll get the error you saw.
Two options that may help are:
Specify an exact version of dependencies (don't use ^ ahead of version)
upgrade Flutter/Dart to at least 2.10/2.16
flutter upgrade
If your problematic package (hooks_riverpod: ^2.0.0 in your case) is listed with ^, it'll use the latest version that doesn't break dependencies.
I'm guessing that when you created a new project and used that same dependency version, upon initial pub get it downloaded a newer version of the package (or a newer version of a dependency that that package uses) into "pub cache" which is relying on the new Error API method.
Your project will store this information in:
<your_project_dir>/dart_tool/package_config.json
The min Dart SDK version listed for the package should normally have changed from 2.12 to 2.16. (update: it's been updated now) This would give us a hint that we need to update our Flutter/Dart if we see our build failing.
In an earlier version of this answer, I noted that the ^ prefix on package dependency versions is supposed to prevent these types of issues, but I'm no longer certain it was meant to cover this situation where the underlying platform needs to be updated (as opposed to a breaking change in the API of the package itself).
Anyways, at first glance, it might make sense to go from 2.0.0 to 3.0.0 for a package version # when it depends on a new core Dart API method that did not exist when 2.0.0 was published.
Notes
The author of riverpod also wrote the new API for Error.throwWithStackTrace so likely the latest version of hooks_riverpod is using the latest API changes. (The version you're listing 2.0.0 is pre-release currently). You could try earlier versions of riverpod in your pubspec.yaml (such as 1.0.3)
for anyone facing " Method not found: 'Error.throwWithStackTrace' " with firebase.
try to add this to your pubspec.yaml
dependency_overrides:
firebase_messaging_platform_interface: 3.1.6
I saw this.
How about trying flutter pub upgrade?
If it is not resolved, then check analyzer version and check which dependency locks that.
As noted in Baker's answer, Error.throwWithStackTrace was recently added in Dart 2.16.
If you're getting an error about Error.throwWithStackTrace not being found for some package, the package author neglected to update their package's minimum Dart SDK version. You should report that to the package maintainer. In the meantime, you should use an earlier version of the problematic package or use a newer version of the Dart SDK.
Try running flutter upgrade
By this it will upgrade your flutter and dart SDK version and hope it resolves your issue
if you are still facing the issues after "flutter upgrade" or you use this line of code in pubspec.yaml
dependency_overrides:
firebase_messaging_platform_interface: 3.1.6
you receive this type of errors
java.lang.AssertionError: annotationType(): unrecognized Attribute name MODULE (class com.sun.tools.javac.util.UnsharedNameTable$NameImpl)

so Try to upgrade your gradle version, this line in your build.gradle
classpath 'com.android.tools.build:gradle:4.1.0'
after doing that it may be possible it ask you to change your
gradle-wrapper.properties
distributionUrl=https://services.gradle.org/distributions/gradle-6.1.1-all.zip
to
distributionUrl=https://services.gradle.org/distributions/gradle-6.5-all.zip
also upgarde this packages
firebase_core: ^1.10.0
firebase_messaging: ^11.1.0
Recently I've updated to flutter 2.5 and the newest androids studio, and tried to compile my flutter project to android device. Android studio throws me the error below. If I write flutter run in a terminal there is no problem compiling to android device.
Guess this must be related to android studio. I tried downgrade to an earlier android studio version, but the problem persists.
I'm not sure what plugin this is, it doesn't seem like any I use in my project.
Edit: If I downgrade flutter from 2.5 to 2.0 my project compiles again. So the problem is within flutter 2.5
Launching lib/main.dart on Android SDK built for x86 in debug mode...

../plugins/flutter/.pub-cache/hosted/pub.dartlang.org/photo_view-0.11.1/lib/src/core/photo_view_gesture_detector.dart:106:29: Error: The argument type 'PointerEvent' can't be assigned to the parameter type 'PointerDownEvent'.
- 'PointerEvent' is from 'package:flutter/src/gestures/events.dart' ('../plugins/flutter/packages/flutter/lib/src/gestures/events.dart').
- 'PointerDownEvent' is from 'package:flutter/src/gestures/events.dart' ('../plugins/flutter/packages/flutter/lib/src/gestures/events.dart').
super.addAllowedPointer(event);
There was an API change in version 2.5 of flutter and several packages must update accordingly.
Your logs show that the exact package which contains the error is photo_view.
Luckily enough the package has just been updated to fix this, so just update its version in your pubspec.yaml:
photo_view: ^0.12.0
UPDATE
If you don't have the package directly in your pubspec
You have two options
1 It's probably a transient dependency, you can run flutter pub deps
to list the installed packages and its dependencies and try to update the one that uses photo_view (if it does have an update)
2 Add a dependency override to your pubspec.yaml, this will effectively override the version of the package being used
dependency_overrides:
photo_view: ^0.12.0
Add this just before your dev_dependencies
from your debug code
('../plugins/flutter/packages/flutter/lib/src/gestures/events.dart').
you open the file or click if there are link clickable
Search for this:
void addAllowedPointer(PointerEvent event) {
and replace with this:
void addAllowedPointer(PointerDownEvent event) {
Here is the reference link
https://flutter.dev/docs/release/breaking-changes/gesture-recognizer-add-allowed-pointer
This problem arises due to the GestureRecognizer Cleanup -
Here is the documentation if you are intrested in the migration code
But in case you just want to build your flutter app without any migrations following are couple of solutions to that problem
You can update photo_view dependency in your pubspec.yaml file to
photo_view :^0.12.0
If you do not want to update your dependency due to any reason you can opt for this temporary fix . In the pubspec.yaml file add the following custom photo_view with better gesture recognition in dependency_overrides.
dependency_overrides:

I update the Flutter latest stable version 1.20.1 when I click the run button on an already existing project it shows me this error:
Could not resolve the package 'characters' in 'package: characters/characters.dart'.
But when I create a new project and try to run it works.
Following the Github issue below, it is a common issue after upgrading to a different Flutter Version
Could not resolve package characters
In my case, I resolved the issue with flutter clean.
In latest version of razorpay_flutter 1.1.4 I have encountered a gradle exception could not open cp_proj remapped class cache for eii7mfeilb85f6s74q7cms80e.
The issue is in this unknown statement.
SOLUTION:
Go to flutter\.pub-cache\hosted\pub.dartlang.org\razorpay_flutter-1.1.4\android.
In build.gradle remove package android line and save.
Now this will work perfectly.
I have an ionic 3 app that we have been using in production. I just did a new clone of the repo and tried to build the android version. It fails with:
com/ionicframework/common/IonicCordovaCommon.java:61: error: cannot find symbol
assetManager = cordova.getContext().getAssets();
^
symbol: method getContext()
location: variable cordova of type CordovaInterface
src/com/ionicframework/common/IonicCordovaCommon.java:116: error: cannot find symbol
Context c = cordova.getContext();
^
symbol: method getContext()
I did not change anything in the code base -- and it was working well a few hours ago before the clone of the repo.
This is due to a plugin. The package.json had the following spec:
"cordova-plugin-ionic": "^5.3.0",
Turns out the latest version of the plugin is not compatible. To fix, just change to
"cordova-plugin-ionic": "5.3.0",
That is stick to 5.3.0 -- and not later version.
Remove plugin:
cordova plugin rm cordova-plugin-ionic
Add older version
cordova plugin rm cordova-plugin-ionic#5.3.0
This fails with
cordova plugin add cordova-plugin-ionic#5.3.0
Variable(s) missing (use: --variable APP_ID=value --variable CHANNEL_NAME=value).
To fix remove platform android and add again.
cordova platform rm android; cordova platform add android#6.4
Once done, the build using
cordova build android
and see it succeed.
