I want to implement ViewModel into my app, but I cant import viewModels()

CodePudding user response：

To use ViewModel in your app, you will need to add the following dependency in your build.gradle file:

implementation "androidx.lifecycle:lifecycle-viewmodel-ktx:2.2.0"

Then, declare a ViewModel in your activity, fragment, or other class. For example:

private val viewModel: GameViewModel by viewModels()

Finally, use the ViewModel within your activity by calling its methods and properties.
