Create table from two lists dart - list

Question

I want to turn the two lists (shown below) into a table sort of like this:
Faults | Severity
motor velocity: 7 | 3
Using faultItems[i] with corresponding severityList[i]. I want to be able to show the table in a Flutter app using dart. Any help is greatly appreciated!
faultItems list
[motor velocity: 7, motor velocity: 2, motor temp: 6, motor temp: 3, motor temp: 9, motor temp: 4, motor temp: 7, motor temp: 8, motor temp: 2, motor temp: 5, no motor comm]
severityList list
[3, 3, 2, 2, 2, 2, 2, 2, 2, 2, 3]
code:
List<int> severityList = [0];
List faultItems = [0];
var lastFault;
var pairs = new Map<String, int>();
Widget _buildFaultOutput(snapshot) {
severityList.clear();
faultItems.clear();
//New growable lists with 0 set as the first value to prevent error
var msg = snapshot.data;
var faultList = msg["fault_list"];
var numberOfFaults = faultList.length;
if (faultList.length == 0) {
return Text("None");
} else {
for (var i = 0; i < faultList.length; i++) {
// print(faults);
// print("i: $i");
var faults = faultList[i];
var motorCurrent = faults["fault"];
var severity = faults["severity"];
if (motorCurrent != lastFault) {
faultItems.insert(i, motorCurrent);
severityList.insert(i, severity);
// print('added ${faultItems[i]}, severity: ${severityList[i]}');
lastFault = motorCurrent;
} else {}
//TODO: add list of faults with key/value pairs (fault:severity): Text of "motorCurrent" in color of severity
//TODO: Print each individual item from list with severity
// return Text(
// "Number of Faults: ${faultList.length}\n$faultItems\nSeverity: ${severityList[i]}");
for (var i = 0; i < faultItems.length; i++) {
pairs[faultItems[i]] = severityList[i];
}
print('$faultItems');
print('$severityList');
}
return Text(
"Pairs: $pairs\nNumber of Faults: ${faultList.length}\n${faultItems}\nSeverity: ${severityList}");
}
}
