How The argument type ‘String’ can’t be assigned to the parameter type ‘int’ Error Occurs ?

I am fetching data from API and I am using data from API to Text Widget in flutter. But it is showing an error about data type that’s:

Card(
              child: Container(
                child: Text(data[index]['name']), //error red underlying with 'name'
                padding: EdgeInsets.all(15),
              ),
            )

How to Solve The argument type ‘String’ can’t be assigned to the parameter type ‘int’ Error?

Solution 1

Simple Solution is You have to set data variable to List type. Just Like Below Example.

  List data = [
    {"name": "john"}
  ];

Now you can use data variable name parameter with your index. Same as below.

Card(
              child: Container(
                child: Text(data[0]['name']),
                padding: EdgeInsets.all(15),
              ),
            )

Your error must be solved by this solution.

Solution 2

The reason is that http.get can’t work with strings anymore. You need to use Uri to parse the HTTP address.

I had the same issue which I fixed it with this approach:

var url = Uri.parse("https://your_api");

then call it like this (attaching the http):

http.Response response = await http.get(url);

This should work.
