水平













曖昧さ回避
 「水平面」はこの項目へ転送されています。ヒトの解剖における水平面については「横断面」をご覧ください。


水平（すいへい）とは、静かな水面のように傾きがなく平らなさま。重力が働く方向に垂直な面を水平面（すいへいめん、Horizontal plane）という。水平方向と言う場合、水平面に対して平行な方向となる。対して、水平面に対し垂直なさまを鉛直と言う。


水平を測るための道具として水平器がある。

I tried all solutions from that topic with/without GlobalKey for Scaffold and Form but the problem wasn't fixed. I tried to build a authentication form with login and signup.
