This can be done in `preBuild`, in one of two ways:
46
47
1. Packaging the tool with `buildDartApplication`, adding it to Nixpkgs, and running it like any other application
48
-
2. Running the tool from the Pub cache
49
50
Of these methods, the first is recommended when using a tool that does not need
51
to be of a specific version.
52
53
-
To use the second method, first make the derivation accessible within itself (e.g. `let self = ...; in self`), and then run it from the Pub cache in `preBuild`.
54
55
e.g., for `build_runner`:
56
57
```bash
58
-
dart --packages=.dart_tool/package_config.json ${self.pubspecLock.dependencySources.build_runner.packagePath}/bin/build_runner.dart build
59
```

Do _not_ use `dart run <package_name>`, as this will attempt to download dependencies with Pub.

For the second method, the `packageRun` function from the `dartConfigHook` can be used.
54

This is an alternative to `dart run` that does not rely on Pub.

e.g., for `build_runner`:
57

```bash

packageRun build_runner -- build

# Usage:
16

# packageRun <package> [executable] [bin_dir]

# By default, [bin_dir] is "bin", and [executable] is <package>.

# i.e. `packageRun build_runner` is equivalent to `packageRun build_runner build_runner bin`, which runs `bin/build_runner.dart` from the build_runner package.
