Build: Could not find package "build_runner". Did you forget to add a dependency?

[zgramming]

Thank you for taking the time to file an issue!

In order to route, prioritize, and act on this as soon as possible please include:

• Dart SDK Version (dart --version)
  Dart VM version: 2.7.0 (Fri Dec 6 16:26:51 2019 +0100) on "windows_x64"

• What package(s) from this repo you are using, and the version (i.e. build_runner 0.7.12)
  build_runner: ^1.7.2

  I implement Modularization in my project. first i create packages with name network with run command flutter create --template=package network, i reference this.
  This packages include models of my project. after that i create model user ,then run command build the model flutter packages pub run build_runner build --delete-conflicting-outputs :

import 'package:hive/hive.dart';

part 'user_model_hive.g.dart';

@HiveType()
class UserModelHive extends HiveObject {
  @HiveField(0) 
  DateTime id;
  @HiveField(1)
  String giverName;
  @HiveField(2)
  String pinCodeNumber;

  UserModelHive({this.id, this.giverName, this.pinCodeNumber});
}

But i get error like this
```
Could not find package "build_runner". Did you forget to add a dependency?
pub finished with exit code 65

i'm sure already include build_runner in my packages network pubspec.yaml.

For information on the generic Dart part of this file, see the

following page: https://dart.dev/tools/pub/pubspec

The following section is specific to Flutter.

flutter:
# To add assets to your package, add an assets section, like this:
# assets:
# - images/a_dot_burr.jpeg
# - images/a_dot_ham.jpeg
#
# For details regarding assets in packages, see
# https://flutter.dev/assets-and-images/#from-packages
#
# An image asset can refer to one or more resolution-specific "variants", see
# https://flutter.dev/assets-and-images/#resolution-aware.
# To add custom fonts to your package, 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 in packages, see
# https://flutter.dev/custom-fonts/#from-packages
```

It's my structure Folder if you needed.

You definitely have the build_runner dependency. Maybe you are running from the wrong directory? You need to run from the network directory not your root.

[zgramming]

@jakemac53 After move to network directory , It's solved the problem!. Thank's.
I can close the issue now.

I'm having the same problem. What do you mean by "need to run from the network directory"? and does your answer apply to a Linux system?

[jakemac53]

network was just the name of the directory that their package lived in.

You need to run from the directory where your pubspec.yaml lives for your package.
