### Layer
|
|
|
|
To use this configuration layer, update your custom configuration file with:
|
|
|
|
```toml
|
|
[[layers]]
|
|
name = "lang#dart"
|
|
```
|
|
|
|
### Syntax checking && Code formatting
|
|
|
|
To enable syntax checking and code formatting in spacevim,
|
|
you need to install [dart sdk](https://github.com/dart-lang/sdk).
|
|
|
|
### Install dart-repl
|
|
|
|
You need to install the dart_repl via pub, pub is a build-in package manager in dart-sdk:
|
|
|
|
```sh
|
|
pub global activate dart_repl
|
|
```
|
|
|
|
## Layer options
|
|
|
|
- `dart_sdk_path`: Set the path of dart sdk, by default, it is `''`.
|
|
|
|
