Flutter array in Text Widget-CodePudding

I have an array that contains a list of String

var array = [
    "table",
    "laptop",
    "kitchen",
  ];

and I have a random number:

int i= Random().nextInt(2);

I want to show the random selected item in a text widget something like:

Text("your randomly selected item ist $array[i] ")

but that dosn't work.

How can I do that?

CodePudding user response：

You have to use ${array[i]} instead of $array[i].

CodePudding user response：

When you want to use more than on variable value in string context, you should use {} like:

Text("your randomly selected item is ${array[i]}")

CodePudding user response：

You have to use like this:

var array = ["table","laptop","kitchen"];

int i= Random().nextInt(array.length);

Text("your randomly selected item ist ${array[i]} ");
