Nope. This answer doesn't work this time for me.

When I run flutter run, I get:
Running "flutter packages get" in townsquare...
The current Dart SDK version is 2.1.0-dev.0.0.flutter-be6309690f.
Because flutter_circular_chart 0.0.3 requires SDK version >=1.19.0 <2.0.0 and no versions of flutter_circular_chart match >0.0.3 <0.1.0, flutter_circular_chart ^0.0.3 is forbidden.
So, because mobile depends on flutter_circular_chart ^0.0.3, version solving failed.
pub get failed (1)
This is my pubspec.yaml
name: mobile
description: A new Flutter project.
version: 1.0.0+1
dependencies:
flutter:
sdk: flutter
cupertino_icons: ^0.1.2
carousel: ^0.0.1
http: "^0.11.3+16"
validate: "^1.6.0"
url_launcher: "^3.0.2"
shared_preferences: "^0.4.2"

flutter_local_notifications: ^0.3.6
dev_dependencies:
flutter_test:
sdk: flutter
assets:

- images/logo.png
- images/bg_viewer.jpg
With the above, please enlighten me, what's wrong?
That's is because you are using : Dart version 2.1.0-dev.0.0.flutter-be6309690f and the plugin named flutter_circular_chart has a constraint
https://github.com/xqwzts/flutter_circular_chart/blob/master/pubspec.yaml
environment:
sdk: '>=1.19.0 <2.0.0'
You can fork the project and update the sdk constraint and ref to your repository:
Like this:
flutter_circular_chart:
git: https://github.com/your_repo/flutter_circular_chart.git
Note
Also would be fine if you open an issue in their repo to notify the devs about the issue that you have.
Use devendency_override with same version witch need for same for other dependency.
Like google_maps_flutter: ^0.5.28+1 needs intl to be 0.16.0
then craete dependency_overrides:
intl: ^0.16.0
below of dev_dependencies:
flutter_test:
sdk: flutter
run project until it not run on device.
Enjoy. Thanks..

The Problem:
I have an app that uses sembast and shared_preferences to store data.
Recently I Accidently Downgraded my app which caused it to lose all data stored.
I tested it in both physical as well as Emulator device both result in the same issue.
is there a way to fix this?
Note: By "fix this" I mean to prevent further data loss in case of downgading not the recovery of the lost data)
Steps to Reproduce:
1)Create a project
2)Store data in shared -references or sembast
3)Hot restart
4)Change build number to a lower number than the previous build (Ex: 1.0.0+110 to 1.0.0+109)
5)Hot restart

Error appears when performing
flutter build apk --release
and
flutter build apk
There is no error when I build the APK without having the firebase_admob
The built failed likely due to AndroidX incompatibilities in a plugin. The tool is about to try using Jetfier to solve the incompatibility.
Building plugin firebase_admob...
The plugin firebase_admob could not be built due to the issue above.
I have performed
flutter doctor --android-licenses
flutter clean
The error still appears.

The change was gradle-4.10.2-all.zip to gradle-5.1.1-all.zip

It's probably caused by the r_scan library as it uses custom implementation of the X509TrustManager. See this issue.
I'm trying to install flame but whenever I run the pub get it gives me a really long error "Because every version of flutter_test from sdk depends on xml 3.6.1 and tiled >=0.4.0 depends on xml ^4.2.0, flutter_test from sdk is incompatible with tiled >=0.4.0."

I had the same problem today and checked on the Flame Discord channel.
They told me they have a conflict with their lib with stable flutter channel.
Recommendation is to change to Flutter Channel Beta.
I did that, then did Flutter Upgrade, then finally Flutter Pub Get and it worked.
Terminal Commands
To check which channel you are currently on
Flutter Channel
To change to the beta channel
Flutter Channel Beta
To get the beta version
Flutter Upgrade
So, when I have the same problem with you when I tried it.
Here's my solution:
In your dependencies: section inside the pubspec.yaml file, change the flame section without any version tag:
dependencies:
flutter:
sdk: flutter
cupertino_icons: ^0.1.3

When loading my flutter app on my IOS device in the android developer IDE, the app loads as normal, but images are not loaded onto the app until I click the "Run 'main.dart'" button again. Once my device is disconnected from my computer and I restart the app, the images never load.
The only advice I can find on anything close to this is "Your yaml file must be wrong". I assure you I've checked my pubspec yaml half a million times and cannot find any errors. Besides, the images DO load when the phone is connected to my computer, but only after running the app a second time after it's installed and run the first time. Any help is much appreciated!! My pubspec.yaml file and flutter doctor -v output are below. Thanks again!

Instead of defining each image, you can just provide the folder path like this:
assets:
- images/
Change name of image file in images directory and in pubspec.yaml file like this:
assets:
- images/welcome_to_Bill.jpg
- images/bill_description.jpg
- images/bill_description2.jpg
- images/bill_description3.jpg
Then run this command flutter pub get.
Did you check the initState() function? There might be a missing setState() call in one of the load function.
setState() {
// You can initialize a list here, if you have a list that images use.
}
This solved the issue when I tried adding elements to the list in setState() function while loading.
