## Public functions
### aarMetadata
```
fun aarMetadata(action: @ExtensionFunctionType AarMetadata.() -> Unit): Unit
```
Options for configuring AAR metadata.
### consumerProguardFile
```
fun consumerProguardFile(proguardFile: Any): Any
```
Adds a proguard rule file to be included in the published AAR.
This proguard rule file will then be used by any application project that consume the AAR (if proguard is enabled).
This allows AAR to specify shrinking or obfuscation exclude rules.
This is only valid for Library project. This is ignored in Application project.
This method has a return value for legacy reasons.
### consumerProguardFiles
```
fun consumerProguardFiles(vararg proguardFiles: Any): Any
```
Adds proguard rule files to be included in the published AAR.
This proguard rule file will then be used by any application project that consume the AAR (if proguard is enabled).
This allows AAR to specify shrinking or obfuscation exclude rules.
This is only valid for Library project. This is ignored in Application project.
This method has a return value for legacy reasons.
## Public properties
### aarMetadata
```
val aarMetadata: AarMetadata
```
Options for configuring AAR metadata.
### consumerProguardFiles
```
val consumerProguardFiles: MutableList
```
ProGuard rule files to be included in the published AAR.
These proguard rule files will then be used by any application project that consumes the AAR (if ProGuard is enabled).
This allows AAR to specify shrinking or obfuscation exclude rules.
This is only valid for Library project. This is ignored in Application project.
### multiDexEnabled
```
var multiDexEnabled: Boolean?
```
Returns whether multi-dex is enabled.
This can be null if the flag is not set, in which case the default value is used.
### signingConfig
```
var signingConfig: ApkSigningConfig?
```
The associated signing config or null if none are set on the variant dimension.
