Develop Reference

Dependency resolves to version 2.9.0 in pubspec.lock but we want to use version 2.7.1

We are trying to integrated Firebase_crashlytics in our App but because our App is built on an older version of Flutter (it doesn't support Null Safety) so we can't use the latest version. Then we decided to integrate version 2.7.1 or lower but the pubspec.lock file always resolves the version to 2.9.0 which is null safe and it throws build error for our App not being null safe.
Can anybody guide me as to what should I do or not do in this regard?

I have tried almost everything I found on stackoverflow, github, ...
such ass flutter clean
flutter pub get
I have tried rebuilding my gradle also downgrading flutter
All help is very welcome and I look forward to what you all find
If you need more information please let me know

I also had this kind of issue. Mine was with awesome_notifications after I had upgraded flutter.
I had to swap it out for local_notifications. Try replacing geolocator.

Execution failed for task ':app:compileFlutterBuildDebug' Flutter 2.2.0

I have been facing this issue after I reset the Android Emulator as it got hanged while development so I just wiped the data. And since then I am facing this issue only for this specific project while for other projects they are working fine.

💻 Solution Tried
Reinstalling flutter
Tried clearing the packages & getting them again
flutter clean

Tried deleting pubspec.lock and running flutter pub get
Removing rm android/settings.gradle and running flutter create .
Tried removing C:/USERNAME/.gradle and C:/USERNAME/.gradle/caches both
Tried upgrading Android Studio
Tried upgrading flutter to flutter 2.2.3 the latest version!
Tried replacing settings.gradle code with the below one:
include ':app'
def flutterProjectRoot = rootProject.projectDir.parentFile.toPath()
def plugins = new Properties()
def pluginsFile = new File(flutterProjectRoot.toFile(), '.flutter-plugins')
if (pluginsFile.exists()) {
pluginsFile.withReader('UTF-8') { reader -> plugins.load(reader) }
}
plugins.each { name, path ->
def pluginDirectory = flutterProjectRoot.resolve(path).resolve('android').toFile()
include ":$name"
project(":$name").projectDir = pluginDirectory
}
Any help would be appreciated, Thanks!
And please let me know if you need anything else for better understanding :)

If you're using outdated plugins and recently ran flutter upgrade, it's possible that cache of outdated packages is still kept and causing the issue. What you can try doing here is run flutter pub get and flutter pub upgrade if outdated versions were displayed on the logs. Running flutter pub outdated to upgrade the package versions should also work.

Asset Images not showing up in FLutter Web when doing flutter run -- release

When I was trying to execute my flutter project as
flutter run
The screenshot is the display
All the assets display as intended.
But when I use
flutter run --release
The screenshot is the display
No asset displays and blank stuff is displayed instead
I have tried most fixes already available but nothing worked so far. I have put changed the image's location to be outside the assets folder but still no luck.

Flutter Unable to read manifest info from app.apk

i have upgraded the flutter four days earlier and since then i am facing issue, the workspace has no errors as other collaborator's code is running fine.
Error is:
Error running com.xxxxxxxx.signals. Default activity not found
Unable to read manifest info from F:\Projects\xxxxxxxx-mobile\xxxxxxxx-mobile\build\app\outputs\apk\app.apk.
No application found for TargetPlatform.android_x86.
Is your project missing an android\app\src\main\AndroidManifest.xml?
Consider running "flutter create ." to create one.
i ran following commands in Visual Studio Code Terminal:
flutter clean
flutter run
the solutions i applied which unfortunately didnt work are:
Then i changed branch of the repository i have working in
Switched to dev, beta branches of flutter
Re installed emulator
attached real device

I encountered a similar problem and o fixed it by deleting the app.apk in the build/app/outputs/apk directory and it worked.

I resolved this by these step.
upgraded flutter
created new other project using flutter create foo
compared foo project with my project
removed kotlin setting from my project
changed androidx to android.support packages in gradle dependencies
copied and modified *.iml files for my project (although these files are ignored)
flutter clean
flutter run
I used VS editor.
My Project dependencies. pubspec
dependencies:
flutter:
sdk: flutter
flutter_localizations:

firebase_database: ^2.0.2
firebase_storage: ^2.1.0+1
video_player: ^0.10.0+4
chewie: ^0.9.7

in my case it happened cause I defined an intent filter for notification inside main application tag in manifest and declared an application service that receives it in manifest after main application tag and that is wrong
The right to change main application tage name to the new application tag not to put the both

This Error is because the flutter does not find the SDK path. You just need to set the SDK Path by following the command using the terminal.
flutter config --android-sdk $SDK_PATH
