我知道如何使用標準TextField，但我想創建一個TextField如圖所示的，是使用的類TextField還是有另一個類？

你可以suffixIcon在InputDecoration
TextField(
decoration: InputDecoration(
suffixIcon: //Your widget
suffixIconConstraints: //Widget constraints
)
)

更改Icons并hintText根據您的要求...
TextFormField(
decoration: InputDecoration(
contentPadding: EdgeInsets.only(right: 10.0, left: 20.0),
fillColor: Colors.grey.shade700,
focusColor: Colors.grey.shade700,
filled: true,
hintText: "Enter or paste address",
hintStyle: TextStyle(color: Colors.white),
border: OutlineInputBorder(
borderRadius: BorderRadius.circular(80.0)
),
suffix: Container(
padding: EdgeInsets.symmetric(vertical: 2.0,horizontal: 10.0),
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(80.0),
color: Colors.white,
),
child: Row(
mainAxisSize: MainAxisSize.min,
children: [
Icon(Icons.person,color: Colors.orange,),
Icon(Icons.person,color: Colors.orange,),
],
),
)
),
),
SizedBox(
height: 10.0,
),
TextFormField(
decoration: InputDecoration(
contentPadding: EdgeInsets.only(left: 20.0,right: 10.0),
filled: true,
fillColor: Colors.grey.shade700,
focusColor: Colors.grey.shade700,
hintText: "Amount",
hintStyle: TextStyle(color: Colors.white),
border: OutlineInputBorder(
borderRadius: BorderRadius.circular(80.0)
),
suffix: Container(
padding: EdgeInsets.symmetric(vertical: 2.0,horizontal: 10.0),
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(80.0),

您可以使用容器并根據需要進行裝飾，并將 Textfield 用作其子項，添加后綴圖示
要么
使用 Container（具有邊框半徑和顏色）并在 Container 內部使用 Row 并相應地放置 TextField 和另一個容器（具有邊框半徑和顏色）。
Container(
height: 50,
width: double.infinity,
margin: EdgeInsets.symmetric(horizontal: 20.0),
decoration: BoxDecoration(
color: Colors.grey,
borderRadius: BorderRadius.circular(50),
),
child: Row(
children: [
Expanded(
child: TextField(
textInputAction: TextInputAction.next,
controller: name,
autofocus: false,
decoration: InputDecoration(
hintText: ' Enter or paste address',
hintStyle: TextStyle(
fontSize: 20, color: Colors.white),
),
),
),
Container(
height: 40,
width: 48,
decoration: BoxDecoration(
color: Colors.orange,
borderRadius: BorderRadius.circular(50),
),
),
SizedBox(width: 10,)
],
),
);

結果
這是自定義文本欄位小部件（它只是一個包裝器）。您可以傳遞任何邊框顏色、半徑、填充顏色、填充或不填充...等

這是一個簡單的呼叫你的小部件。
