I'm trying to create a flowchart adapting the code from Header in tikz container for flowchart but the blocks are not centralized (I can't upload the image).
The code I used:
\documentclass[12pt]{article}
\usepackage{tikz}
\usepackage[active,tightpage]{preview}
\usetikzlibrary{shapes,arrows.meta,calc,fit,backgrounds,shapes.multipart,positioning}
\tikzset{box/.style={draw, rectangle, rounded corners, thick, node
distance=7em,
text width=6em, text centered, minimum height=3.5em}}
\tikzset{every node/.style={font=\scriptsize}}
\PreviewEnvironment{tikzpicture}
\setlength\PreviewBorder{4pt}%
\begin{document}
\tikzset{block/.style={rectangle split, draw, rectangle split parts=2,
text width=14em, text centered, rounded corners, minimum height=4em},
grnblock/.style={rectangle, draw, fill=green!20, text width=10em, text centered, rounded corners, minimum height=4em},
whtblock/.style={rectangle, draw, fill=white!20, text width=10em, text centered, minimum height=4em},
line/.style={draw, -{Latex[length=2mm,width=1mm]}},
cloud/.style={draw, ellipse,fill=white!20, node distance=3cm, minimum height=4em},
container/.style={draw, rectangle,dashed,inner sep=0.28cm, rounded
corners,fill=yellow!20,minimum height=4cm}}
\begin{tikzpicture}[node distance = 1.25cm, auto]

Besides I'd like to align the icons of the "Constitute" block on the left.
Could anyone help me with these changes?
