These both may be bugs with the currently released version of MAUI.

This bug was recently posted and there is already a fix for the Switch to address this issue.

I fixed it by changing uses value to

This is a bug in GCC. C 2018 6.10.3.2 specifies behavior of the # operator. Paragraph 1 says “Each # preprocessing token in the replacement list for a function-like macro shall be followed by a parameter as the next preprocessing token in the replacement list.” We see this in the #x of #define STR_(x) #x.

Paragraph 2 says:

If, in the replacement list, a parameter is immediately preceded by a # preprocessing token, both are replaced by a single character string literal preprocessing token that contains the spelling of the preprocessing token sequence for the corresponding argument. Each occurrence of white space between the argument’s preprocessing tokens becomes a single space character in the character string literal. White space before the first preprocessing token and after the last preprocessing token composing the argument is deleted…

The X(Y,Y) macro invocation must have resulted in the tokens Y and Y, and we see in #define X(x,y) x y that they would have white space between them.

White-space in a macro replacement list is significant, per 6.10.3 1, which says:

Two replacement lists are identical if and only if the preprocessing tokens in both have the same number, ordering, spelling, and white-space separation, where all white-space separations are considered identical.

Thus, in #define X(x,y) x y, the replacement list should not be considered to be just the two tokens x and y, with white space disregarded. The replacement list is x, white space, and y.

Further, when the macro is replaced, it is replaced by the replacement list (and hence includes white space), not merely by the tokens in the replacement list, per 6.10.3 10:

… Each subsequent instance of the function-like macro name followed by a ( as the next preprocessing token introduces the sequence of preprocessing tokens that is replaced by the replacement list in the definition (an invocation of the macro)… Within the sequence of preprocessing tokens making up an invocation of a function-like macro, new-line is considered a normal white-space character.

There are two ways to solve it.

in your json package there is a package named "react-native-reanimated": "^2.3.0", remove this package and install "react-native-reanimated": "^2.2.4"

and restart metro then build again

This is Clang bug #49513; the situation and analysis is similar to this answer.

sizeof(T)>0 is an atomic constraint, so [temp.constr.atomic]/3 applies:

To determine if an atomic constraint is satisfied, the parameter mapping and template arguments are first substituted into its expression. If substitution results in an invalid type or expression, the constraint is not satisfied. [...]

sizeof(void)>0 is an invalid expression, so that constraint is not satisfied, and constraint evaluation proceeds to sizeof(U)>0.

As in the linked question, an alternative workaround is to use "requires requires requires"; demo:

UPDATE:

For your firebase_core version is seems to be sufficient to pass the FirebaseOptions once you initialize firebase in your flutter code (and you don't need any script tags in your index.html):

It does not default to zero. The sample answer is wrong. Undefined behaviour is undefined; the value may be 0, it may be 100. Accessing it may cause a seg fault, or cause your computer to be formatted.

As to why it's not an error, it's because C++ is not required to do bounds checking on arrays. You could use a vector and use the at function, which throws exceptions if you go outside the bounds, but arrays do not.

I figured out the following with some trial and error:

• Get the "IOResources" node from the IO registry.
• Get the "KeyboardBacklight" property from that node.
• (Conditionally) convert the property value to a boolean.

I have tested this on an MacBook Air (with keyboard backlight) and on an iMac (without keyboard backlight), and it produced the correct result in both cases.

I think this algorithm does what you want, but it's not very efficient. It may provide others with a starting point for faster solutions.
