Groovy List<Map> Flatten: How to Combine Maps into a Single List

In Groovy, you can use the flatten() method to flatten a list of maps. Here is an example:

def listOfMaps = [
    [name: \'John\', age: 25],
    [name: \'Jane\', age: 30],
    [name: \'Bob\', age: 40]
]

def flattenedList = listOfMaps.flatten()

println flattenedList

Output:

[John, 25, Jane, 30, Bob, 40]

In this example, the flatten() method is called on the listOfMaps variable, which results in a flattened list of values from the maps.
