Kotlin Coding Guidelines

Code structure

• short methods (not too long)

  • add suggestion how to refactor

• only one level of abstraction keep only one abstraction level in method

• keep low level of identation less is more for example when() if-else if-else is not very good redable

• use variable for expression / condition

Questions

value.?let or if (value != null)

Is really better to use

value?.let {
     // some block
}

then

if (value != null) {
    // some block
}

There is no return value so block is NOT expression.

Don't use anonymous class implementation

val value = object : Type {
    // implementation
}
