I have added addtional Hive Fields to a Hive type before as needed. I have then deleted .g.dart file and regenerated it with no problems.
This time after added a new Hive Field I have this error and I am not able to understand why

I have tried flutter clean, flutter pub outdated, pub get, etc... and I keep getting this error.
In my pubspec.yaml I have, this worked just fine until I have added the latest Hive Field.
dependencies:
flutter:
sdk: flutter
hive: ^2.0.2
hive_flutter: ^1.0.0
path_provider: ^2.0.1

build_runner: ^2.0.1
hive_generator: ^1.1.0
I found an old post about downgrading analyzer, but this then causes problems with the versions I am using.
In the main.dart there isn't an error on line 33:3. it should not have ; as suggested. Again this worked fine before, so I am not sure why it is an issue now. I also commented out the code here and I still get the same error message even with nothing at line 33:3
If I remove the field I added I still get the same error. If I restore the .g.dart file from a backup I can run the app as before.
Any input on this would be appreciated as it's very confusing
Update:
So I tried deleting the model file and completely recreating it and then generating the .g.dart. I get this:

I have tried keeping the file as it was, added a new Hive Field to a previous Hive Type and adding a Hive type and I get nothing generated.
I haven't changed the existing Hive fields, I know that causes issues. New Hive Fields and Hive Types were given the next number that hadn't been used before.
So I didn't fix the issue, but for a work around I created a new flutter project, copied my code over except any generated files. Then I was able to generate new type adapters after adding new Hive fields and hive types. Maybe something got corrupted in my previous project. Not sure why flutter clean wouldn't fix this. But maybe this will help someone stuck on the same issue.
Set source_gen: 1.0.3 in pubspec.yaml helped in my case.

I am writing a dart source generator that is using json_serializable for some of it models. Initially the source generation was working fine for some time but now when I run dart run build_runner build --delete-conflicting-outputs I am getting error:

Here is the dependencies for my package:
dependencies:
path: ^1.8.1
yaml: ^3.1.0
dotenv: ^3.0.0
recase: ^4.0.0
json_annotation: ^4.4.0
code_builder: ^4.1.0
dart_style: ^2.2.1
dev_dependencies:
lints: ^1.0.0
test: ^1.20.1
build_runner: ^2.1.7
json_serializable: ^6.1.3
And build.yaml looks like this:
builders:
map_gen:
import: "package:map_gen/map_gen.dart"
builder_factories: [ "build" ]
build_extensions: { "$lib$": [ ".map.dart" ] }
auto_apply: dependents
build_to: source
I haven't been able to figure out why this is happening or is there any limitation on using source generator for a package that provides its own generators. Is there any way I can resolve this?
Edit
I am using vscode, but I have tried building from terminal and also getting the same error. Even after running flutter clean | dart pub get | dart run build_runner build --delete-conflicting-outputs same error persists.
Current workaround
Currently I am manually creating .g.dart file and adding the part of statement manually, running build_runner after that results in successful source generation. However if I run build_runner again after I have linked generated methods to my code, the .g.dart files are deleted and again I am facing with the same error. I have to repeat this process every time I want source generation.
I faced the exact same issue and got help from the creator of Drift in Dart Build's Gitter chat room. Quoting the solution here:
you can simply create an empty <project_directory>.build.yaml file in your package's directory. This special build.yaml file will only be used when a build is started from the directory of your package. To the build system, it will look like your builders simply don't exist (and thus it won't attempt to compile them). When you run a build from other packages that depend on your builder package, the <project_directory>.build.yaml file is ignored and all your builders are there.
You can refer to how Drift do it here.
I was using ObjectBox without many problems for a while during a development with Flutter, but now the build_runner fails:
The closest change I have made is a Flutter upgrade yesterday to Flutter 2.5.3 along with Dart 2.14.4.
ObjectBox dependencies in pubspec.yaml are:
objectbox: ^1.2.0
objectbox_flutter_libs: any
Now, although the objectbox-model.json file is there, the objectbox.g.dart file is missing and does not get regenerated.
I then tried to run the two example projects give in the official OB documents, but those failed too with similar results (they ran OK before this).

I have found a solution to this problem and am posting it for the benefit of whoever encounters the same issue in future.
You should manually delete the objectbox-model.json file and objectbox.g.dart (if it still exists) and run the command "flutter pub run build_runner watch --delete-conflicting-outputs" at the project folder (without quotes, of course).
Also, it has to be mentioned that, as at the time of writing this post, if ObjectBox is a contemplated choice for your persistence, please be wary that (although it is an excellent package), support for a problem if you get stuck is very low to nil, in stackoverflow. I have not seen more than 2 or 3 contributors and if your question escapes their attention, you are pretty much on your own!
I did a mistake by migrating to null-safety then every thing become error, after fixing a lot of errors, I still get an error and the error is :

[SEVERE] json_serializable:json_serializable on lib/injection.config.dart (cached):
This builder requires Dart inputs without syntax errors.
However, package:invoice_app/injection.config.dart (or an existing part) contains the following errors.

it's look like injectable generator have some mix up with the new version of dart that is why when I generate new injection.config.dart file then it gave this error
injection.config.dart:18:12: This requires the 'non-nullable' language feature to be enabled.
so if you want to fix it just open the file then then remove the ? mark like from this
_i1.GetIt $initGetIt(_i1.GetIt get,
{String? environment, _i2.EnvironmentFilter? environmentFilter}) {
final gh = _i2.GetItHelper(get, environment, environmentFilter);
return get;
}
to this
_i1.GetIt $initGetIt(_i1.GetIt get,
{String environment, _i2.EnvironmentFilter environmentFilter}) {
final gh = _i2.GetItHelper(get, environment, environmentFilter);
return get;
}
I know it's not a solution but it works until when I will migrate to non-nullable, I will use this.
I am trying to learn moor_flutter so i added some dependencies into pupspec.yaml:
dependencies:
flutter:
sdk: flutter
moor_flutter: ^2.1.1
provider: ^4.0.4
flutter_slidable: ^0.5.4
path_provider: ^1.6.5
path: ^1.6.4
# The following adds the Cupertino Icons font to your application.
# Use with the CupertinoIcons class for iOS style icons.
cupertino_icons: ^0.1.2
dev_dependencies:
moor_generator: ^2.4.0
build_runner: ^1.8.1
flutter_test:
sdk: flutter
After installing these dependencies I create a table class inside lib -> data -> moor_database.dart file:
import 'package:moor_flutter/moor_flutter.dart';
part 'moor_database.g.dart';
class Tasks extends Table {
IntColumn get id =>
integer().autoIncrement().call();
TextColumn get name => text().withLength(min: 1, max: 50)();
DateTimeColumn get dueDate => dateTime().nullable()();
BoolColumn get completed => boolean().withDefault(Constant(false))();
}
#UseMoor(tables: [Tasks])
class AppDatabase extends _$AppDatabase {
AppDatabase()
: super(FlutterQueryExecutor.inDatabaseFolder(
path: 'db.sqlite', logStatements: true));
#override
int get schemaVersion => 1;
}

I asked a question in it's official repo git and i got this answer :
It works if you replace this with integer().autoIncrement()(). The generator should emit a more helpful error message though, I'll take a look at why that didn't happen here.
I chnaged:
IntColumn get id =>integer().autoIncrement().call();
to :
IntColumn get id =>integer().autoIncrement()();
my problem gone.
Following this
And using cli
stagehand web-angular
pub get

Do you know how to fix this?
This is a known issue. A work around is to add the following dependency override to your project's pubspec.yaml:
dependency_overrides:
sass: 1.3.2
