`flow.get_context()` will error when called outside a build function (as you
should not normally do this).
## `gui.Flow` container
`gui.Flow` is a fixed-width container that wraps items around if they don't
fit. Unlike other elements, you must specify a width, and some options like
`min_w` and `padding` aren't supported.
This is similar to GTK's `FlowBox`, but with a lot fewer features.
```lua
gui.Flow{
-- Fits 3 items
w = 3 * (1 + 0.2),
gui.Image{w = 1, h = 1, texture_name = "default_mese_crystal.png"},
gui.Image{w = 1, h = 1, texture_name = "default_mese_crystal.png"},
gui.Image{w = 1, h = 1, texture_name = "default_mese_crystal.png"},
gui.Image{w = 1, h = 1, texture_name = "default_mese_crystal.png"},
gui.Image{w = 1, h = 1, texture_name = "default_mese_crystal.png"},
}
```
