according to the <code>Yoga</code> library

at <a href="https://github.com/facebook/yoga">https://github.com/facebook/yoga</a></p><p> When <code>flex</code> is a positive number, it makes the component flexible

and it will be sized proportional to its flex value. So a

|
component with <code>flex</code> set to 2 will take twice the space as a
|
|
component with <code>flex</code> set to 1.</p><p> When <code>flex</code> is 0, the component is sized according to <code>width</code>
|
|
and <code>height</code> and it is inflexible.</p><p> When <code>flex</code> is -1, the component is normally sized according
|
|
<code>width</code> and <code>height</code>. However, if there's not enough space,
