Struct FlowRowMeasurePolicy 

pub struct FlowRowMeasurePolicy {
    pub main_axis_spacing: f32,
    pub cross_axis_spacing: f32,
}

MeasurePolicy for FlowRow: children flow horizontally and wrap onto the next line when the available width runs out (Jetpack Compose FlowRow).

• Children are measured with loose constraints (min = 0) capped at the incoming max width/height, then packed left-to-right.
• A child that no longer fits on the current line starts a new line; a child wider than the whole line gets a line of its own (and may overflow, like Compose).
• main_axis_spacing separates children on the same line and cross_axis_spacing separates lines; children are top-aligned within their line.
• With an unbounded max width everything stays on one line.

Fields

main_axis_spacing: f32

Horizontal gap between adjacent children on the same line, in dp.

cross_axis_spacing: f32

Vertical gap between consecutive lines, in dp.
