BoolPointer ​

extension BoolPointer on Pointer<Bool>

Annotations: @Since.new('2.15')

Extension on Pointer specialized for the type argument Bool.

Properties ​

value extension read / write ​

bool get value

The bool at address.

Available on Pointer<T extends NativeType>, provided by the BoolPointer extension

Implementation
dart
external bool get value;

external void set value(bool value);

Methods ​

deprecated elementAt() extension ​

Pointer<Bool> elementAt(int index)

DEPRECATED

Use operator + instead

Pointer arithmetic (takes element size into account).

Available on Pointer<T extends NativeType>, provided by the BoolPointer extension

Implementation
dart
@Deprecated('Use operator + instead')
Pointer<Bool> elementAt(int index) =>
    Pointer.fromAddress(address + sizeOf<Bool>() * index);

Operators ​

operator +() extension ​

Pointer<Bool> operator +(int offset)

A pointer to the offsetth Bool after this one.

Returns a pointer to the Bool whose address is offset times the size of Bool after the address of this pointer. That is (this + offset).address == this.address + offset * sizeOf<Bool>().

Also (this + offset).value is equivalent to this[offset], and similarly for setting.

Available on Pointer<T extends NativeType>, provided by the BoolPointer extension

Implementation
dart
@Since('3.3')
@pragma("vm:prefer-inline")
Pointer<Bool> operator +(int offset) =>
    Pointer.fromAddress(address + sizeOf<Bool>() * offset);

operator -() extension ​

Pointer<Bool> operator -(int offset)

A pointer to the offsetth Bool before this one.

Equivalent to this + (-offset).

Returns a pointer to the Bool whose address is offset times the size of Bool before the address of this pointer. That is, (this - offset).address == this.address - offset * sizeOf<Bool>().

Also, (this - offset).value is equivalent to this[-offset], and similarly for setting,

Available on Pointer<T extends NativeType>, provided by the BoolPointer extension

Implementation
dart
@Since('3.3')
@pragma("vm:prefer-inline")
Pointer<Bool> operator -(int offset) =>
    Pointer.fromAddress(address - sizeOf<Bool>() * offset);

operator extension ​

bool operator [](int index)

The bool at address + sizeOf<Bool>() * index.

Available on Pointer<T extends NativeType>, provided by the BoolPointer extension

Implementation
dart
external bool operator [](int index);

operator []=() extension ​

void operator []=(int index, bool value)

The bool at address + sizeOf<Bool>() * index.

Available on Pointer<T extends NativeType>, provided by the BoolPointer extension

Implementation
dart
external void operator []=(int index, bool value);
