taking items from map in flutter - flutter

Question

I am tring to use a map to get words from a string and map them to a widget.
I have tried this but my problem is the key for the words doe and sister get the same keys so i end up getting only one of them
String theText = "my name is doe from http.doe.com, my sister is selly. doe and saqil are not sister friends of koiter.";
wordsMap = Map.fromIterable(text.split(' '),
key: (v) => v,
value: (v) => TextSpan(text: v));
so I tried the code below
Map mapMyWord = {};
// var wordsMap;
var splitForSize = text.split(' ').toList();
for(var t = 0;t<= splitForSize.length-1;t++){
mapMyWord[t] = {'$t':TextSpan(text: splitForSize[t])};
}
but In the second code when I tried to access mapMyWord.values.toList() it returns a list of map data again
[{0: TextSpan("my")}, {1: TextSpan("name")}, {2: TextSpan("is")}, {3: TextSpan("doe")}, {4: TextSpan("````http.codeish.com````,")}, ... ,{19: TextSpan("koiter")}]
so my main problem is how to get the values from here.

Answer 1

It returns maps because you're assigning maps with this line :
mapMyWord[t] = {'$t':TextSpan(text: splitForSize[t])};
So in the end you have a Map<Int, Map<String, TextSpan>>.
If you meant to turn the words of that sentence into a list of TextSpan, this would be the way :
var textSpanList = text.split(" ").map((word) => TextSpan(text: word)).toList();
If you want to do it directly in the widget tree, this would do it :
children: <Widget>[
for(var word in text.split(" "))
Text(word),
]
N.B: This last snippet requires a minimum SDK of 2.2.2 in the pubspec.yaml

In your second code, change the assignment part:
Map mapMyWord = {};
// var wordsMap;
var splitForSize = text.split(' ').toList();
for(var t = 0;t<= splitForSize.length-1;t++){
mapMyWord[t] = TextSpan(text: splitForSize[t]);
}
Then, mapMyWord.values.toList() will only return a list of TextSpan's. And if you want to get some specific value from the map:
int index = 1; //some number
print(mapMyWord[index]); //this will return one TextSpan
