How to order Jenkins Parameters using groovy script - jenkins

Question

I am using this groovy script to parameterize a Jenkins Job:
properties([
parameters([
[$class: 'ChoiceParameter',
choiceType: 'PT_SINGLE_SELECT',
description: 'Select param1',
filterLength: 1,
filterable: false,
name: 'param1',
randomName: 'choice-parameter-5631314439613978',
script: [
$class: 'GroovyScript',
fallbackScript: [
classpath: [],
sandbox: true,
script:
'return[\'Could not get param1\']'
],
script: [
classpath: [],
sandbox: true,
script:
'return["value1", "value2", "value3"]'
]
]
],
[$class: 'CascadeChoiceParameter',
choiceType: 'PT_SINGLE_SELECT',
description: 'Select param3',
filterLength: 1,
filterable: false,
name: 'param3',
randomName: 'choice-parameter-10000000000000000',
referencedParameters: 'param1',
script: [
$class: 'GroovyScript',
fallbackScript: [
classpath: [],
sandbox: true,
script:
'return[\'Could not get param3\']'
],
script: [
classpath: [],
sandbox: true,
script:
''' if (param1.equalsIgnoreCase('value1')){
return["1", "2"]
}
else if(param1.equalsIgnoreCase("value2")){
return["3", "4"]
}
else if(param1.equalsIgnoreCase("value3")){
return["5", "6"]
}
'''
]
]
]
])
])
pipeline {
agent any
parameters {
string(name: "param2", defaultValue: "test1", description: "Test value")
}
stages {
stage ("Example") {
steps {
script{
echo 'Hello'
}
}
}
}
}
If I use this script as is, On the Jenkins job, parameters will be shown in this order: param2, param1, param3. What I really want, is to have them in this order: param1, param2, param3.
From the code as you can see, for param 1 and 3 I am using Active Choice Parameter and Active Choice Reactive Parameter which will be dependent from the value selected in param1. For param2, I need it as string.
Is there a way to achieve this, have them in this order: param1, param2, param3?

Okay, i found that i can use also this in the properties:
[$class: 'StringParameterDefinition',
description: 'Enter param2',
name: 'param2',
defaultValue: '',
randomName: 'string-parameter-1343433232',
trim: true
]
