The solution I developed first splits the data according to the space character. It then uses the GetValue() method to sequentially read the data from each piece. The next step will be to use the data by transforming it accordingly.

This example prints the following output to the console:

[ScanCode=1234, ScanMessage=Test, Itemname=First, ID=1]
[1234, Test, First, 1]

The solution I developed is available below:

void main()
{
   String text = "ScanCode=1234 ScanMessage=Test ItemName=First ID=1";
   
   List<String> original = text.split(' ');
   List<String> result = [];
   
   GetValue(original, result);
   print(original);
   print(result);
}

void GetValue(List<String> original, List<String> result)
{
    for(int i = 0 ; i < original.length ; ++i)
    {
        result.insert(i, original[i].split('=')[1]);
    }
}
