问题

I hope you have a great day, I'm still learning Flutter, and I have some difficulties displaying some data.

So I have this List data

listData = [{someData: Lorem #1, image: linkToSomeImage}]

and I need to display the image using Image.network(image).

But I don't know why. I tried listData[0].image or listData[0]["image"] to populate the variable, but it doesn't work, and I get all the red

What is the correct way to do this?

数据将通过运算符[]和key来访问，因为你有JSON（Map）列表。

listData[0]["image"]

使用方式如下：

Row(
  children: [
    for(int i=0; i< listData.length; i++)
      Image.network(listData[i]['image']),
  ]
)

英文:

As you have the list of json(Map), data will be accessed by operator [] with key

listData[0][&quot;image&quot;]

and usage will be

Row(
  children: [
    for(int i=0; i&lt; listData.length; i++)
      Image.network(listData[i][&#39;image`]),
  ]
)
