Is there any way to set the max size of the Expanded or Flex widget in Flutter?

Containers constraints are not working at all.

Row(
  children: [
    Container(
      decoration: BoxDecoration(
        color: Colors.red,
      ),
      child: SizedBox(
        height: 30,
        width: 50,
      ),
    ),
    Flexible(
      child: Container(
        constraints:
            const BoxConstraints(minWidth: 50, maxWidth: 100),
        decoration: BoxDecoration(
          color: Colors.blue,
        ),
        child: SizedBox(
          height: 30,
        ),
      ),
    ),
    Container(
      decoration: BoxDecoration(
        color: Colors.green,
      ),
      child: SizedBox(
        height: 30,
        width: 50,
      ),
    ),
  ],
),

What I want:

2. Limiting the width of the Row itself:

   SizedBox(        //wrap your Row with a SizedBox and give it some width
        width: 200, 
        child: Row(
     children: [
       Container(
   

Result:

Edit: As you want to have an adaptable container you just need to change some things:

Row(
 mainAxisAlignment: MainAxisAlignment.spaceBetween, //add mainAxisAlignment to give spaceBetween the containers
  children: [
    Container(
      decoration: BoxDecoration(
        color: Colors.red,
      ),
      child: SizedBox(
        height: 30,
        width: 50,
      ),
    ),
    Container(
      height: 30, //give you container some height instead of a child SizedBox
      constraints:
        BoxConstraints(minWidth: MediaQuery.of(context).size.width/10, maxWidth: MediaQuery.of(context).size.width/5), // add responsive constraints which change values according to your screen size
      decoration: BoxDecoration(
      color: Colors.blue,
      ),
      child: Expanded(child: Container(),) //give it an Expanded widget to take in all the maxWidth
    ),
    Container(
      decoration: BoxDecoration(
        color: Colors.green,
      ),
      child: SizedBox(
        height: 30,
        width: 50,
      ),
    ),
  ],
),

And then you'll get this:
