How to make responsive content in Container Flutter - flutter

Question

How can I make the responsive Content in Container,
when I put anything in a container and the Height content is oversize what is the solution for this? I need to fix it when the user input too much information about the post and I warp it with less/more plugins and when the user uses it the screen is over pixel for sure
I use media query on the container that means I fix the size is okay so it's will happen if too much text
