Struct DrawerTheme 

pub struct DrawerTheme {
    pub shape: Option<ShapeBorder>,
    pub end_shape: Option<ShapeBorder>,
    pub width: Option<f32>,
    pub background_color: Option<Color>,
    pub border_color: Option<Color>,
    pub border_width: Option<f32>,
    pub radius: Option<f32>,
    pub elevation: Option<f32>,
    pub shadow_color: Option<Color>,
    pub scrim_color: Option<Color>,
}

Defaults for Drawer.

The rounding is on the inner edge only — the one that meets the content — and the outer edge stays square against the window it is docked to, which is what the reference’s own shape resolves to. Which edge that is follows the direction: the panel does not know which side of the screen it landed on until it paints.

Fields

shape: Option<ShapeBorder>

What shape a leading panel is — the reference’s DrawerThemeData.shape (drawer.dart:268). Unset, the framework rounds the panel’s inner edge by DRAWER_RADIUS.

end_shape: Option<ShapeBorder>

And a trailing one — the reference’s endShape (drawer.dart:269), which is a separate field rather than a mirror of the first because a panel’s rounded edge is the one facing the page, and that is the opposite side.

A trailing panel does not fall back to shape: a theme that named only the leading panel’s shape has said nothing about the other one, and the framework’s own default is a better answer than a shape rounded on the wrong edge.

width: Option<f32>

The panel’s width.

background_color: Option<Color>

The panel’s fill.

border_color: Option<Color>

The hairline on the panel’s inner edge.

border_width: Option<f32>

That hairline’s thickness; 0.0 removes it.

radius: Option<f32>

The rounding of the inner edge’s two corners — the edge that meets the content. The outer one stays square against the window.

elevation: Option<f32>

How far off the surface the panel sits. 0.0 casts no shadow, and neither does a height with no shadow_color.

shadow_color: Option<Color>

The shadow’s colour. Unset, transparent, as the reference’s Material 3 drawer is (its defaults, line 795): a panel is lifted by its tone, and shadowed only on request.

scrim_color: Option<Color>

The scrim behind a modal panel, alpha included.
